Случайно нашел довольно интересную статью, если кто возьмется перевести пришлю оригинал на почту. Ironman Hawaii, my special subject, and special for itself! The next few pages will give you some very interresting informations about this event and the triathlon itself, and the materials that are used! -Why -Why The main question that is asked to triathletes is: why do you do this? And in fact it's a very good and authorised question. It's always said that little sport helps you to keep fit, but these athlets are not fit, they are machines, they are ready to accept 8 ore more hours of going on the thin line between total debility and the all overlaping feeling of finishing. This would also be the main reason why people do the ironman, it's the incredible feeling of satisfaction while running down the last few meters up to the finsh, your whole body ignores all the pain that grew during the competition, and this gives you the heebie-jeebies of your life. The whole body sends out adrenaline and you feel like crying and screaming at the same time. I don't know it for sure, but when i look at finishers that documentations of that sport show I think I'm quite right with my thoughts. I have never done an Ironman so far but I'm sure, in 3 years time, I'll be ready to do it. An additional goodie is, that you can do the same track the pros do. There are not many sports you can compare that to. And until the year 2004 you where also able to start shoulder by shoulder beside the stars of this incredible sport. But then they changed the rules so that the women pros don't get irritated by the age groupers. But it's still the same track... -Main knowledge about the triathlon - Triathlon was invented in France around 1920, it was a 3km run that followed a 12km bike race and a river crossing. This sport was forgotten some time after it's invetion and in 1978 it got reinvented on Hawaii. 15 brave people combined the 4km Waikiki rough water swim with the bikerace around Oahu and the Honolulu Marathon. In the end 12 of these 15 brave souls reached the finish. It was the first step of a succesfull story. Althoug the next year only 14, including the first woman started, they kept on orgnisating the event. And they earned what they deserved: 106 Starters on the 3rdrd attempt. From there on the Numbers were constantly rising towards 1000 and even higher. Because of the rising number of competitors, the ironman comitee decided to move over to BIG Island in 1981, to Kona where it is still held today as the inofficial World Championship. -The tree disciplin- At first we have the swim, most times in calm waters like lakes or river basins. Then the bike ride follows, often, there are loops to complete, like in Austria or Arizona. But Hawaii has only one long course to manage. After finishing the ride the run waits for you, often loops again, and like the other disciplines it's length depends on the-> -Different distances : The shortest is the SprintSprint Sprint , but don't think it's easier! When it is not „long“, it is much faster because you don't have to divide your energy so everybody gives full speed ahead. The swim would be about 700 metres the bike 20km and the run 5 km Next comes the Olympic Distance. It's the double sprint distance (1400/40/10) as it's name says it's the triathlons representative at the Olympic games and first held in Sydney 2000. It's also the distance that helped Kate Allen on the last few metres to Olympic gold. The next step is the Half Ironman (from the year 2006 on it'll be called 70.3 and there will be held an official worldchampionship in Florida) We also have one of these in austria its called Viennaman and it's swim is held in a side basin of the danube, (2km/90/20) The Longdistance is the most popular and breathtaking event of all distances but, incredible but true not the longest! Also there has to be said that longdistance is not always Ironman. For example in Austria we have the Podersdorf triathlon over the 3.8-180-42, but this event hasn't got the ironman license, so you won't be able to qualify for Hawaii. Also longdistance isn't always 3.8-180-42, there are numerous events, that don't belong to the ironman series these events consist out of 4km swim 120 bike and 30 run. The Ultra distance (2-times Ironman) and the Decathlon (10 (!) times ironman) are for people that set no limits to their bodys leisure. -Time chip - To enable a quick take-up into the end-result list, with all the split times and other time concerned figures nearly at every triathlon and other events where time is important a time chip is used. There are many different companies that offer these little helpful things, so I wont start to name them all (just two that are quite popular in Austria: PENTEK and SPORT TIMING AG). In the following picture it is shown how you can place a time chip. At marathons, you can also interlace it into the shoelaces. At bike races you'll have to put it onto the rear chainstay. Of course in a triathlon you can't put your time-chip onto the bike or interlace it into the laces, because you won't carry that stuff with you during the swim:-) So in a triathlon it is common to put it onto your ankle (the side doesn't matter). The chip-name itself can vary from race to race because of the different products. While paying the entry fee, you'll have to pay a little more, because of the refund for the chip, but you'll get it back when you give your chip back after the race. If you don't do that, you practically bought the chip and you can use it at any other event that uses the same product.
-Triathlon gear
-Two posibilities: -Racesuit: One piece suit with a zip on the front or on the back side, element of cloth is already worked into the racesuit, just like in normal bike shorts. The material should be fast drying and tight because when you wear a loose one it will interfere you while swimming and later on while running and cycling it will probably excoriate. -Two parts set: Consisting of a Tri Top... and a Tri Short or a Tri Brief ...where also some different kinds are available (with or without zipp, with pockets on the back, shorter ones to have a free belly...) And the big advantage is that this two parts make going to the toilet much easier. Tri Top with brief A longer version of the Tri Top with Tri Shorts.
-Transition area -

The transition area is the place where you change from swim to bike or from the bike to the run. In smaller events it's mainly one single station because there are not that many people, but at a bigger event like the Ironman where there are nearly 2000 men and women having their racing machines and other nesessary items waiting for them in the transition area it would be a huge mess. So the solution is, to divide the bike stuff from the running stuff. Time is taken twice, when you enter and when you leave, after race you can see how many time you won or lost compared to your mates. This looks like this (compare to the picture above): Yellow: Medical station, you go there (if you still can do that) if you feel crappy Light Blue: Penalty Box, when you have to sit in there you probably brought other competitiors into dangerous situation or you simply didn't keep the prescribed 5 meter distance to the rider in front of you. In the section rules I'll accomplish that more exatly. Dark Blue: WC Orange: The press, like in any other sport, the major press sits in there to present the event to the world. (Ironman-LIVE even broadcasts the race live over the net (last October I spent 6h watching :-) ) Puke-green: The transition tent, it's the place where you can change the gear, put on shoes etc... Yellow1: The transition bags, these bags contain your running shoes and other accessories like hats or power gels, beverages,... Yellow2: The bikepark, like a parking lot with a warranty of many thousand Euros The worst thing that could happen to me at an ironman would be, not to find my bag, I even had nightmares about it :-). Find your bag: About 2000 competitors and as everybody needs the running accesseries there'll be 2000 bags. -Rules: Maybe the most important rule concerns the slipstream while racing on the bike. It depends on the race if „slipstreamriding“ is allowed. In the Austrian championships in Duathlon for example slipstream driving is allowed. While in the ironman race you have to keep 5m (earlier it was 10m) away of your frontman. And while overtaking anybody you have to keep 2m distance to this competitor also you would just have a short period of time to do it, but in reality while riding these 180km nobody really takes care. In the race there are the so called Marshalls, these guys are ordered to mark anybody who did anything wrong. If they do so you might have to make a short stop either in the penalty box at the end of the bike-course back in the transistion area again or just at that point you got seen breaking a rule. The penalty time on long distances is rated by about 8 minutes, but on ironman events this time could probably vary. For a very hard violation of roules you can even get kicked out of the race by getting shown the red card by a racemarshall. The aerobar (example HED S-bend) is only allowed at events where slipstream is not allowed at the other races you'll have to use a conventional road racing bike, with an aerobar that doesn't go any further than both brakes do (picture below) This is a picture of my bike, unfortunately i don't have the right aerobar for those races, so I'll go without but the red line would show how long the aerobar should be. An example for such a bar would be the FSA Mini Other Rules: During the swim your number has to be on the back of your hand or on your upper arm (it gets painted on there). Before going onto the bike course the race number has to be picked up in the transistion area, also the helmet has to be put on before you move the bike. The number has to be at the back while cycling (ergometring :-) While going onto the run the number has to be turned onto the front side. Another rule is that up to a special water temperature, you are not allowed to wear a neoprene any more in Olympic and Sprint distance races. And if the water is beneath a special temperature, you HAVE to wear a neoprene. -Special knowlege about Ironman Hawaii -Special knowlege about Ironman Hawaii-Special knowlege about Ironman Hawaii-Special knowlege about Ironman Hawaii-Special knowlege about Ironman Hawaii-Special knowlege about Ironman Hawaii -Special knowlege about Ironman Hawaii -Special knowlege about Ironman Hawaii-Special knowlege about Ironman Hawaii -Special knowlege about Ironman Hawaii-Special knowlege about Ironman Hawaii-Special knowlege about Ironman Hawaii -Special knowlege about Ironman Hawaii -Special knowlege about Ironman Hawaii -Special knowlege about Ironman Hawaii -Special knowlege about Ironman Hawaii-Special knowlege about Ironman Hawaii -Special knowlege about Ironman Hawaii -Special knowlege about Ironman Hawaii -Special knowlege about Ironman Hawaii -Special knowlege about Ironman Hawaii -Special knowlege about Ironman Hawaii -A Hawaii slot -A Hawaii slot -A Hawaii slot -A Hawaii slot -A Hawaii slot-A Hawaii slot -A Hawaii slot-A Hawaii slot is a ticket for the competition offered on every Ironman Event and on some 70.3 series races. -Qualification -Qualification-Qualification -Qualification-Qualification -Qualification-Qualification -Qualification It is possible to get to hawaii without having realy qualified for it, the name of the game is „Ironman lottery“, where you can apply for a slot. This is a bit complicated because it is split up in two groups, US citizens and non US, there is also the Passport-club, something like a membership, like in a golf club. Altogether there are as I get it 200 slots, 150 are for the US, 50 for the rest of the world. 100 of these slots in america get to those mentioned Passport-club-members, the rest goes to anybody who can prove a finished triathlon longdistance within 12 month. If you have won a slot you have to complete either an Ironman or a 70.3 event to validate it. To get a slot under „normal“ conditions, you have to finish a race (Ironman or special 70.3 event) in a leading position of your age group or the pro group. An example: In Austria 2005 we had three Hawaii slots for the men in the age Group of 18-24. That means, if you are under the first three finishers of this group you are qualified. The trip to hawaii will cost about 7000? that you will have to pay the day after the event when there is a big party where the comitee reads out those names that had qualified. If in the mentioned example you would be 4thth you still have a chance, because if one in front of you refuses the ticket, it goes over to the next one, that would be you then. It doesn't matter what nationality you belong to, that gives the same chances for all. There are currently 27 events with Hawaii slots all around the world. 7 of these 27 are 70.3 Half Ironmans. -6- Swimming with friends -7- You'll have to swim against huge waves, in salt water, that forces you to vomit very easily, for 3.8km. But there are hightec equipment parts that will make life a little bit more easier... -The neoprene: -The neoprene:-The neoprene: -The neoprene:-The neoprene: -The neoprene:-The neoprene:-The neoprene:-The neoprene:-The neoprene: The two main things a neopren is there for are on the one hand to swim faster by getting a better swim position, on the other hand, it prevents you from cooling out. Although you won't have that problem in the pacific. Speed: Neoprene is a material where many small gas bubbles are evenly spread over the whole medium. These bubbles cause that the swimmer has a more optimal position by lifting him more out of the water so the whole movement gets more effective. The modern Neos even have a surface that's similar to shark skin. The neoprene suits are also called wetsuits. When stepping into the water, a little bit of water will get inside the suit. There it will be between body and neoprene, it gets heated by the body and regulates the temperature. From outside it is isolated by the neoprene. Most neoprenes have a different material thickness, for example the torso has 5mm while the moving areas (legs and arms) have 2mm. To get on in this „skin“ a zip at the back helps, at most models like (Somewhere around 20 thousand bucks. Maybe that's the prize you have to pay for an endless experience in a small pool... -9- Go like Hell(riegel)! While riding up and down Hawaiis demanding bikecourse, you'll constantly have to face strong winds. This wind, called Mumuku, is also the cause why disc wheels are not allowed at Hawaii, but despite this it is said, that athlets got blewn of the street. You may think the wind would cool you down, but its still very hot, about 1500m of ascent to overbear. -10- -Evolution of the bike -Evolution of the bike-Evolution of the bike -Evolution of the bike -Evolution of the bike -Evolution of the bike-Evolution of the bike -Evolution of the bike-Evolution of the bike-Evolution of the bike The iron runner: At first there was „this“(Peugeot „Super Competition“): The gearshift is on the lower pipe, an iron frame (-->heavy!) Wheelset with many spokes (about 36 to 48 per wheel) I wasn't able to find any weight dates on the net but as I have driven such a bike for a while I'd guess it's weight is about 14-17 kilos, somewhere between these both... The more aerodynamic way This type of bike was standard for quite a long time, in 1985 a specialisation into a more aerodynamic bike shape took place. This is Scott Tinley with the mentioned bike, which is also Peugeot, maybe it has to be mentioned that in the Tour the France these days it was one of the best bikes... So what he actually changed or did, was this more aerodynamic base bar he installed. And it worked after the „bike“ he had the lead and won the race in the end. By the way, today such a base bar wouldn't be possible any more because the rules won't allow anyone whose bike brakes show to the front to start. The Premiere: 1987 the year the first aerobar appeared. It was Dave Scott on his way to his sixth and last title and again Scott Tinley. The gearset is still on the lower pipe of a quite heavy frame. But the improvement of the aerodynamics was enormous. And also the arms had the chance to recover from the hard swim. Up to 1990 many triathletes have settled over to the new technology. From now on nearly every year new inventions where put together on the way to a perfect bike for this sport. The gearshift found it's place at the aerobar, the first carbon-frames where offered, and the weight started to sink towards 8 kilos. On the next page you will find some of the very best examples of what kind of bikes can be build today. -11- Some tri-bikes to get the flavour:Some tri-bikes to get the flavour: Some tri-bikes to get the flavour: Some tri-bikes to get the flavour: Some tri-bikes to get the flavour:Some tri-bikes to get the flavour:Some tri-bikes to get the flavour:Some tri-bikes to get the flavour:Some tri-bikes to get the flavour: Some tri-bikes to get the flavour: Some tri-bikes to get the flavour: Some tri-bikes to get the flavour: Some tri-bikes to get the flavour:Some tri-bikes to get the flavour: Some tri-bikes to get the flavour:Some tri-bikes to get the flavour: Some tri-bikes to get the flavour: This is Cervelo's P3, the newest weapon against time. It came out 2005, was first used by CSC cyclist Ivan Basso during the time trial stages of the Giro. Concerning triathlon, it took South African Tri Pro Raynard Tissink to victory in Austria. The frame alone costs about 3000$. The shown wheelset called zipp 999 costs about 2000$, both full carbon. This is the Kuota Calibur in combination with the Campagnolo Bora wheelset. For 2.500$ the frame is yours. In 2004 it was Norman Stadler who claimed the Ironman Hawaii tiltle with this bike. The Cannondale Ironman 6000 as said built for the mission Ironman is an aluminium bike in the range between 1500-2000$ per frame. Such a Cannondale was used by this years Hawaii-winner the German Faris al Sultan. Road Bike ----> Tri Bike ?! When we talk about bikes, there are two relevant categorys: time trial/triathlon bikes, and road bikes. What is the difference? At first of course the physical apearance, while the road bikes, have a thin and fragile looking frame the tri bikes seem to be more „beefy“. This has to do with the aerodynamic. Beefy of course means a little bit more weight than the road bikes, but when you are riding against headwind for 180km solo, you will be thankfull for more aerodynamic. The new generation of road bikes also goes into that direction but not that extreme. What you can see on many new road bikes is that the seat tube „tries to follow“ the wheel, marked red in the fotograph below (Trek Madone 5.9). The Scott SR1 Plasma is the demonstration that it is possible to combine lightness with aerodynamic, only 7.4 kilos make it to one of the worlds lightest time trial bikes and it also comes near to the lightest road bikes. -12- Another difference and also an important one is the seat tube angle, 75°-78° are usual for TT bikes. This is important because when attaching an aerobar clip on a normal roadbike, of aproximately 73°, it means that when you rest your arms on the aerobar, you streck your body and the top of your pedal stroke makes your feet touch your stomache and after a while this will cause back pain. But with 78° this can't happen, you sit in a more aerodynamic and of course more comfortable position ergo you feel fresher when you go onto the run. Summed up, the triahtlon bike has the 75 to 78° to prevent you from suffering back pain, it allowes you enough space to breath normally and you are better against the wind you will ride faster and much more comfortable. It is possible to convert a normal bike into something that comes near a tribike, therefore you'll need clip on bars, and a „knicked“ seatpost: The seatpost brings you near to the 75-78°, but as said it will never be as good as a real time trial bike, just a compromise. Above we have heared about aerobars, and clip on bars, but what are these things? You can't really say if there are more athletes using an aerobar or a clip on bar. The bar itself is used at Ironman events since 1987. -the Aerobar: -the Aerobar:-the Aerobar: -the Aerobar:-the Aerobar:-the Aerobar: -the Aerobar: -the Aerobar: The main reason for putting an aerobar onto your bike is to stay in an aerodynamic position as long as possible. This works because of the shift gear thats on the end of the extentions of the bar. Just when using the brakes you will have to leave the position. Even while drinking you won't have to grab down for the bottle each timeor. There are tanks like the profile desighn aerodrink that get possitioned right in front of you between the two extentions. Only for refilling you have to grab down to the bottle cage, take one out and squeeze the water or whatever into the open aerodrink. Because of a sponge the water quickly floads into the tank, and will stay in there even when ride up a mountain roughly. The mountains are the natural foes of the cyclists. And there you could probably get problems with the aerobar. To be able to shift, your hands have to be at the front but when riding up it is often more prefered to stand up to put more pressure into the strokes but I guess this might just be a problem for somebody who has just started using an aerobar. If you choose an aerobar on a long distance race, you'll never be wrong. Most aerobars are available in alu and carbon. -Clip on bar: -Clip on bar:-Clip on bar:-Clip on bar:-Clip on bar: -Clip on bar: -Clip on bar: -Clip on bar: These bars are often used on a normal road bike on short distances and on long distances as well. If you don't want to buy a tri bike its some kind of compromise, because it can be put off and on quickly. -13- -CARBON and ALUMINIUM -CARBON and ALUMINIUM-CARBON and ALUMINIUM-CARBON and ALUMINIUM -CARBON and ALUMINIUM-CARBON and ALUMINIUM -CARBON and ALUMINIUM-CARBON and ALUMINIUM -CARBON and ALUMINIUM -CARBON and ALUMINIUM-CARBON and ALUMINIUM-CARBON and ALUMINIUM-CARBON and ALUMINIUM-CARBON and ALUMINIUM-CARBON and ALUMINIUM The two main materials that modern tri bikes are made of are carbon and aluminium. -Aluminium bikes, are probably the most common bikes, light and comparatively cheap towards the carbon and titan bikes. To improve the handling, many bikes have combinations between carbon and alu. So there are bikes that have a carbon rear because carbon abates better and enables a soft ride. There are just many companies that apply that technique and many Pros that use it. This is Torbjorn Sindballe on his Argon18 Mercury on his way to a new overall record on the bike trial of this years IM Hawaii. He completed the 180km in 4:21:36. From the seat tube backwards it's all carbon. The price of these frames is generally around 1600$ . -Carbon frames have the advantage that you can create new shapes. Perfect examples is the Cheetah. Natascha Badmann (swiss/six time Hawaii champion) uses this bike. It has 26“wheels and the most amazing thing about this frame is that it's a frame and water bottle in one, this causes a higher aerodynamic. -14- -WHEELS 4 THE PROS: -WHEELS 4 THE PROS: -WHEELS 4 THE PROS: -WHEELS 4 THE PROS: -WHEELS 4 THE PROS:-WHEELS 4 THE PROS:-WHEELS 4 THE PROS:-WHEELS 4 THE PROS: -Disc wheel (and combinations): -Disc wheel (and combinations):-Disc wheel (and combinations):-Disc wheel (and combinations):-Disc wheel (and combinations): -Disc wheel (and combinations):-Disc wheel (and combinations):-Disc wheel (and combinations):-Disc wheel (and combinations):-Disc wheel (and combinations): -Disc wheel (and combinations):-Disc wheel (and combinations): -Disc wheel (and combinations): -Disc wheel (and combinations):-Disc wheel (and combinations):-Disc wheel (and combinations): -Disc wheel (and combinations): -Disc wheel (and combinations):-Disc wheel (and combinations): The intention behind the disc wheel is to cause as less possible air velocity as possible. Which will make the bike faster. But the disadvantage is a higher weight and the fact that it is very fragile towards sidewinds. That's why it isn't allowed on Hawaii. But on nearly all other events the Pros have one. I would like to use the Cervelo P3 C to show how the frame and the aerodisc work together. There is hardly any space between the tube and the frame. And as you can see below the frame is built like a knife, ready to cut the wind and lead it over the disc. The wheels that are mounted on the picture are called „Zipp 999“ the front wheel with a 81mm high carbon rim, the rear wheel a full carbon disc with a golfball like structure. Costs about 2000$ But it is possible to get aerodynamic much cheaper with nearly or even the same quality. The Stinger 90 and the „Lenticular-light Disc“by HED „only“ costs about 1300$ and weigh about 2 kilos, the Zipp 999 Combnation weighs about 1.5 kilos, there is now the question, if you are ready to pay 700$ more just for half a kilo. Cycling is not cheap....if you want to get rid of a kilo this will often cost you 1000$. -Tri Spoke and the Fourspoke: -Tri Spoke and the Fourspoke:-Tri Spoke and the Fourspoke: -Tri Spoke and the Fourspoke:-Tri Spoke and the Fourspoke: -Tri Spoke and the Fourspoke:-Tri Spoke and the Fourspoke: -Tri Spoke and the Fourspoke:-Tri Spoke and the Fourspoke: -Tri Spoke and the Fourspoke:-Tri Spoke and the Fourspoke: -Tri Spoke and the Fourspoke: -Tri Spoke and the Fourspoke:-Tri Spoke and the Fourspoke:-Tri Spoke and the Fourspoke:-Tri Spoke and the Fourspoke: -Tri Spoke and the Fourspoke:-Tri Spoke and the Fourspoke: Like the disc wheel the Tri- and Fourspokes are actually used to make the bike as aerodynamic as possible, it has nearly the same effect the disc wheel has, and since disc wheels are forbidden as a front wheel the Tri and Fourspokes have that position. Also a major advantage of these wheels is their extreme stiffness, that is important to bring the power you put into your strokes onto the street and convert it into speed. But in case of weight they can't concurise with the Carbon wheels like the HED Stinger 90 and the ZIPP 808. Of course every company says that their wheel is the fastest, the price is also nearly the same: only the Bora is a bit higher. XENTIS :1349? HED 3 Carbon: 1280? HED Stinger 90: 1184? ZIPP 808: 1560$ Campagnolo Bora: 1700? -15- -HED 3 (Tri Spoke): -HED 3 (Tri Spoke): -HED 3 (Tri Spoke): -HED 3 (Tri Spoke):-HED 3 (Tri Spoke): -HED 3 (Tri Spoke):-HED 3 (Tri Spoke): -HED 3 (Tri Spoke):-HED 3 (Tri Spoke): Is a very popular wheel, it can be used as an alternative for the disc wheel, for example on Hawaii, or in combination with it, or as a wheelset itself with front and rear HED 3s.

Their main advantage is the low weight. But when there is low weight you can be sure about a high price. And because of the material you need special brake pads. Worst case that could happen, would be to have a puncture, so that the rim contacts the tarmac, it can happen that the rim brakes. The whole wheel would irreparable damaged. -Alu wheels: -Alu wheels:-Alu wheels:-Alu wheels: -Alu wheels:-Alu wheels:-Alu wheels:-Alu wheels:-Alu wheels:-Alu wheels: In my opinion Alu wheels can absolutely compete to their relatives made out of carbon, the shape is the same, just a little more weight and a little less stiffness make them different and the fact that they deform, under high pressure the carbon doesn't deform, it brakes, but in the end both are fucked up.

Now I can't say I just start with the most important part because they are all necessary... A: The rim band: this band is between the rim and the tube, to prevent the tube from getting cut up by the endings of the spokes that are fixed in the rim. B: The tube: it's important for a comfortable ride, to have the right amount of pressure in it. It also depends on the tire.(in this case about 7-8 bars, depends on the weight of the driver, the optimal pressure is shown at the package of the tire). The white powder you can slightly see on the tube is there to enable it to slip around and find the best position. C: the tire: a special combination of rubber is used to minimize the rolling drag, enable a good adhesion and a long life. D: would be the rim. This (picture) is an example for a clincher tire, where the tire and the tube are seperated. There is also the posibility of so called „tubular“ tires. There the tire and the tube are sewn together and the whole thing is glued onto the rim, this has the advantage of beeing able to put more pressure into the wheel (about 11bar) and reduce the rolling drag a little more, negative effects would be that having a puncture will be a serious problem. While riding downhill it is possible that the tire heats up that much that the glue melts and the whole thing jumps of the rim.

They have only one flap, while normal shoes have 2 or more. (Erox Tri Phoon) This one lash system s very practical because most athlets have their shoes already cliped onto the bike when leaving the transition area, all they do then is hop onto their machine, slip into the shoes and with one handhold the shoes are closed while with normal shoes you have to bend down twice or more each side. -Time trial helmet... -Time trial helmet... -Time trial helmet... -Time trial helmet...-Time trial helmet... -Time trial helmet... -Time trial helmet...-Time trial helmet...-Time trial helmet... -Time trial helmet... ...gives you a maximum of aerodynamic, but to a high price: the air ventilation in those helmets is very bad so it gets very hot in there.
