Don't do it.*
*Do it.
edit: What GI are you running? maybe try something a bit easier before swapping cranks.

Not specifically the GI I have a prob with, it's more the range of movement when I really get going. Got a lot of metalwork in one leg.
'Tis for a new build anyways so I have the choice....

mike burrows reckons that shorter cranks are better. He uses 150mm ones and recommends them for people with limited movement.

I run 165s and always have. Allows for higher rpm so can use a lower gearing to get same speed which works for my legs.

I think he went shorter than that for his son? and set his bike up with 120mm or something around that.
The problem is people have pre conceived ideas on what length a crank should be, and as we know Mike loves to challenge those ideas!
He does state to give it a few weeks for the body to acclimatise rather than just do a quick 10 miles and stating something is rubbish. -

these are people opinions
and im sure there right for them
but i like to try stuff out for my self and see if it suits me -

I prefer 165 to the 170 I have on my regular ride. I wish I had the spare cash to switch to 165 on all my bikes.

170's are better for climbing

I'll swear by 165. have it on both my fixed bikes.
As Corney would shout, spin to win Bayybee, spin to win.But probably just my short legs.

I was under the impression they were supposed to match your inside leg length?
Apparently for short arse legs like mine 165mm are the ticket. However Pifko who is has far longer legs than me also runs 165s.

Just think what he could have done on 165s :-)

It should be calculated relative to your frame (body not bike) and to what you like.
I hate when people engaged in sports succumb to the limited range of motion in their joints, that, my friends, is a slippery slope.

Definitely prefer 165. It takes me longer to get tired than with 170's, so they must be more efficient for my legs. Obviously I'm not tall.

And I'm shorter than you running 172.5 on both geared and fixed bikes.
If clearance is tight you might want shorter cranks, as you'll avoid hitting your wheel against your foot when cornering, which can be annoying, and also pedal strike on the floor, which can kick you off line and make you crash if its bad enough.

It should be calculated on efficiency and what feels best. This may or may not have anything to do with your frame. The problem is this would take a lot of experimenting and a high cost, which I guess is why people just stick within the limits of the mass market.
Thinking of going this route...bad leg makes a good spin a bit painful on 170s.
Talk me in/out of it....
