I am continually asked what the huge contrasts are between street bicycles and marathon bicycles. The conspicuous contrast is the way that one races a marathon in an air position, however some of the time we see aerobars on street bicycles so what is the genuine distinction? There is a more modest distinction between uci legitimate time preliminary bicycles and marathon bicycles, however they look fundamentally the same as. The short answer is, street bicycles are intended to have three hand positions, marathon bicycles are intended to have one. Because a street bicycle has cut on aerobars, it doesn’t suggest that it is a reason constructed marathon bicycle.
Draft legitimate marathons are the one zone where a street bicycle is utilized with little stub aerobars, yet positionally speaking, I call them street bicycles. They are intended to have the option to do all that a street dashing bicycle does and truth be told, bike racers utilize the air position of a draft lawful marathon runners constantly.
Time preliminary bicycles that are uci lawful have saddles that are interfered with farther than marathon bicycles. The bicycle is arrangement so the rider needs to really ride on the button of the seat (on the bolt, as is commonly said) to get the legitimate equilibrium point for the exertion being created. The harder one pedals, the farther forward their equilibrium point moves. Since a period trialist is dashing at max exertion, the most effective position is before the agreeable point on the seat, so riders simply intense it out. They don’t need to be agreeable and their occasions are infrequently more than about an hour so what difference does it make? Visit :- จักรยานไตรกีฬา
Marathon bicycles are intended to be ridden for longer distances and at a submaximal pace. This implies that the rider will put more weight on the seat and aerobars in light of the fact that they are not beating the pedals adequately hard to help themselves. All things considered, the seat and aerobars are situated in the spot the rider is the most effective or generally streamlined. The explanation I recognize the two is conventional marathon positions are exceptionally far forward to oblige a long distance runner’s more prominent hip point needs and to permit a super air position.
My concern with this position is twofold. To begin with, the position isn’t amazing and numerous long distance runners surrender more force than is acquired by unadulterated optimal design. Second, the further forward one is situated comparative with their equilibrium point, the more front stacking happens on the knees and overcompensation by quadriceps happens. This muscle unevenness is paid for in the progress and the beginning of the run.
The ideal marathon position is where the rider is as solid and air as could reasonably be expected, with enough solace to have the option to remain in the aerobars the whole occasion. This is a big deal. On the off chance that you need to sit up during a competition to rest on the grounds that the air position isn’t maintainable, you have an issue. You will be going increasingly slow will be more exhausted in the run. Keep in mind, however, power bests streamlined features to a point, so your best position may not be the place where you think it is!
Since the situation on the bicycle and the arrangement of the bicycle to help that position are the two characterizing contrasts between a street bicycle and a marathon bicycle, shouldn’t something be said about all the air tubing on certain casings and the round cylinders on others? Some casing makers promote how quick their edges depend on air stream testing, however I believe that is a ton of showcasing publicity generally. Here is a basic actuality: The piece of the time preliminary or marathon bicycle that makes the most drag is the rider! The edge is inside the limit layer and as such doesn’t make as large a commitment to optimal design as one would might suspect.
