old man knees and crank arm length
« on: July 17, 2017, 12:50:02 AM »
sometimes I need to pedal a mile or two across town aand it sucks and hurts my knees. i got a smaller sprocket, skinnier/faster tires ....will longer crank arms also help out?

at5'8'' Ive always ran 175mm cranks, but should I now consider longer ones for more leverage??
...I have recently heard everyone ranting and raving about 170s and 165s

Depends what's aggravating your knees. If it's the pressure of pushing on the pedal, then sure, longer cranks will help. Just as you guessed, cranks are a indeed a lever

If you're riding a bmx across town your knees will probably hurt regardless of crank length.

I have absolute shit knees and the 165 crank length has been magical. I've gone 165 on all my bikes bmx, mtb, road. I lost a little in leverage, but I got used to that quickly. Key advantage beyond feet closer together for a more centered base is on the over/top stroke since my knees do no have to bend as far with the shorter arm.

Having a higher seat also prevents you from bending them too much. Can't ride with low seat anymore.

I was talking about standing and pedaling.
