I've recently developed pain at the front of my knees when cycling. I suspect this is caused by, or at least made worse by, my bike having cranks that are too long for my leg length (172.5mm cranks for 77cm inseam).
Assuming crank length is a factor, a long term solution would obviously be to get shorter cranks. However, I can't afford that right now.
Are there any bike fit adjustments that I could make to open the angle of/reduce the strain on my knees at the top of the pedal stroke? I've already experimented with various seat height and setback changes without much success. I'm prepared to temporarily compromise other aspects of my bike fit, if it would allow my knees to recover.
