|What's up with different crank arm length?||swampman|

|My Fuji with a double has 170mm crank and my bike with a triple has 175mm crank arm length. I never noticed a difference riding. I want to build up my Look 361 with a double and want to know which length I should buy.
Does having a triple or double make a difference on the length of crank I would what?

|It depends on what you like.
Long legged people tend to go to the 175
Short the 170
Mashers tend to go 175
spinners tend to go 170
Not a lot to do with double or triple.

|I've had 170, 172.5 and 175 and they all just feel like pedalling. I've often wondered if I tried 165's and then 180's as a way to find what the difference feels like if I would then be able to discern smaller differences?|

|I have 172.5s on my Fondriest which I rode exclusively until April. I felt and was riding great. Then, I bought my LOOK, and it has 170s. It feels awesome!!! However, now when I ride the Fondy, it makes my knees hurt. So, yes I can tell the difference. It 'may' be the geometry difference, but my knees did NOT hurt before.
Bizarre thing is that on my MTN bike, I ride 175s and it feels fine, but then again, I hate ultrafast spinning.
My two cents.

|I'm a fairly short guy (30 inch inseam) who prefers a slightly longer crank length. I have 170 on one road bike and 172.5 on the other. The 172.5 takes my knee through a longer range of motion, something that keeps the knee muscles from tightening up and getting fatigued. It's something that keeps the knee joint itself a bit more free, too. With my shorter crank, knee pain can eventually rear its ugly head. With my longer crank, knee pain is an extreme rarity. As a matter of fact, it I get onto the 172.5 cranked bike WITH knee pain, by the time I'm ten miles into the ride the pain has gone away!|

|Clearance on cornering is also a factor!|| |
