    Amazing the speeds these guys get up to and it looks so casual and easy for them..
    I’ve been watching the speed of pedal rotation they going at and l’m sure l go at a similar pedal speed but no way do l reach the speeds they do ..
    Can someone explain why these cyclist go so much faster at what seems a similar pedal speed to us ..

    That's what gears are for.
    Same pedal speed + faster road speed = higher gear.

    Having the legs for it is a matter of work and training - if I used the same gears as they do, I wouldn't go faster, my pedal speed would go down.
    For the riders in the bunch, there's also the matter of drafting - they may only be working 1/5 as hard as someone on their own.

    They seem to have bigger front rings as well because they are much fitter and have stronger legs than all of us here.

    Most of us puny amateurs ride bikes with "compact" chainrings with 50/34 teeth. The compact gear system is one of the things that helped road cycling become so popular.

    Professionals will be pushing a 53/39. This makes the bike go faster!

    Wow, I have a 'professional' triple then, at 52-42-30!
    :biggrin:
    And when in the big ring, I can barely turn the damn thing, no matter how fast I go!

    Can you imagine a professional twiddling a granny gear up Alp D'Huez? Cue sound of peloton laughing...

    They are able to turn a larger gear at a high cadence compared to mere average cyclists.

    Eg I can turn a 53*19 at 95rpm. A pro could turn a 53*17/15 at the same rpm and still be in zone 2/3 for heart rate whilst I would be in zone 5

    It takes lots of training to be super strong and have an enormous cardio engine.

    endurance athletes when retirement need a yearr or two of detraining to return their heart to normal size or could possibly face issues later on. They could just continue with a high level of fitness, but it seems alot just want a normal less active lift after professional sports

    Not really as they have to be at least 6.8kg

    Some of the riders weigh about 8st though which helps!

    My breakfast weighs more than some of those guys. Much as I'd have loved to be a pro cyclist, I'm just built totally wrong for it :sad:

    I’m ready for a 52/36 but it’s also important to spin the lower gears much faster for the same speed output to keep your legs fresher for longer. I think 90 rpm should be pretty standard and 105 rpm when really going for it.

    Cant imagine doing the tdf speeds and hitting tarmac in a pair of thin shorts and a jersey!!

    I struggle with a 50-34, i have strong legs but not for turning a crank it seems

    I'm the opposite.......my CV system seems to be good but the old legs just don't want to work these days. Too many lower back/herniated disc/sciatic issues seem to have wrecked my leg strength.
