All things crank length, should i go shorter? | Time trial gains & bike fitting

Hey,
A lot of people have been asking us about their crank length and whether you should be going shorted on the cranks. So we've put together a list of pro's and cons about crank length.

May as well change the crank length because if your wanting to change the front end now with one piece cockpits and routing it’s realistically the only thing

Worth trying mate

Very interesting that, what size are you in cm by the way just curious with you saying 170mm feel best for you
Regards

I have gone a bit shorter over the years but I really dislike the “got go super short” mentality. If crank length didn’t affect power output we would just screwing the pedals into the end of the crank spindle.

[@sondrebergo]

Maybe biomechanics matter? Maybe the best isnt on either extreme? As an opposite example, why arent we producing/using really long crankarms like eg 200mm or even 300mm? "Super short" is only ~5% shorter, which I guess isnt enough of a change to affect power?

​@@sondrebergowell yeah probably a balancing act. If you went super short each stroke would get less power I'd guess and you now gotta spin up like crazy to get anywhere. A longer lever should make each stroke a bit easier I guess so higher gears can be used? But it takes longer for one rotation ? Not entirely sure. But. ...with an ultra long crank even if you could use it. Well. Might be good for out the saddle stomping down on the pedals. Other than that with your knees to your ears you got a huge range of motion now. Thing is you are weaker at the extreme stretch position. at least bodybuilding CZcams told me. Which is why people doing nonsense on the legpress do it at the top of the movement and barely go down. So you'd struggle to put any good power down from all the way in that position.

Yes I dropped to 165 and found I did lot like it

[@michaelhatch1994]

Like if you like, like 175 like or 170 like but like that might like be too like short like, like that's what I like think like.
