To make a long story short, I have a bad knee that limits my cycling - both in power output and duration.
First question: I'm rethinking my idea of crank arm length. I thought a shorter arm (170) would be easier on my knee as the range of motion is less. Now I'm wondering if a longer arm (175) might be better because of the increased leverage. Any ideas?
Second question: My road bike has a 170 and my mtn. bike has a 172.5. I have a 30" inseam by the way and there is no noticable difference in which bike my knee prefers. So today I rode my third bike, an old mtn. bike with 175 arms. I increased my cadence and my knee felt great! Obviously I'll be experimenting with that - and I guess it makes sense that spinning fast is easier on the knee than mashing. But as a general rule, does increasing cadence lessen stress on the knee?
Any feedback would be greatly appreciated!
