Crank Arms

[SportMonkey]

While I know little about bikes, what I can tell you is that a shorter crank arm would be harder to turn and so spinning is harder

You say that, but one of the issues I find with fast cadences is the lack of resistance, so resistance would increase and leg movement would shorten. I am not basing this on having shortened my own arms.

Did you do it yourself or did you buy a shorter crank? I am thinking about getting one but only if it helps the speed.

No, I mean, I'm still on my 170mm cranks, no shortening for me. I just find a slight incline easier to spin on than flat or downhill, so I extrapolated, maybe badly.

I've got 165 cranks on the way to replace my 175s, and will report my experience once fitted.

No he cut his hands off.

Nope, spinning is easier with shorter crank arm lengths and hence why a lot of track riders use 165s.

New cranks arrived this morning. Nice! Will be fitting them tomorrow morning, but then I'm heading down to the west country to start my end to end, so it'll be a couple of weeks before they get a full test.

I used to have 175mm cranks, but build my current bike with 165mm.
I'll join everyone who said that its "spinny".

Shorter cranks = easier to spin & easier on the knees.

(Your crank length should be roughly one fifth of your leg length.)

I like 175mm cranks, but then I do have long legs and big feet.

gaz it sounds like you suffer from Giraffes disease, your arse is too high off the ground.
I suffer from Ducks disease, my arse is to too close to the ground, I've got short legs, might explain why 165 cranks suite me
