crank length-what's too long?(3 posts)

crank length-what's too long?maurizio

I just acquired a bike through a trade and it's equipped with shorter cranks than what I was riding. The bike fits me better, but I can't seem to get on top of the gear as I did with my old frame. I'm wondering if the shorter cranks might play any role.
I've been riding 175mm for 10 years, but this bike has 172.5. I know this is probably more mental than anything.
What is the longest crank I could ride without hurting my knees and/or spin?
I'm 5'10", 159#. My race weight is near 150. The bike is a 58cm.
I've heard of riders my height riding 180's (Lance A. being one of them)...

Depends on your style. No hard and fast rule. If you are a spinner, you will like the shorter cranks. If you are a masher, you will like the longer cranks. Track racers like em small; climbers like em big. If you love the 175's stay with em.

If your legs are used to 175 you could just go with that, especially if you can feel the difference with 172.5. Lots of pros 5'8"-5'10" spin 175s. Had a friend who went from 172.5 to 180. it took his legs a season to get used to spinning them, but he could power up hills better on them, and liked them alot.
