+1 on that. Don’t hurt yourself any more. You might consider running the 165 moments if you’re worried about your knee? All it does is make you more bike-like. (i.e. easier on your knee) When I changed from 165 to 150, I’m not sure I gained any speed at all. Maybe half a mile an hour worth of cruise speed. The 150s just made me able to spin a little faster going downhill, which is rare enough that I almost kind think 165s would be at least as good as the 150s, and less stressful on joints… if I cared only about downhill speed, I’d probably be struggling with 125s, haha. 150-165 probably doesn’t make too much of a difference, though, so if you don’t have them, it’s not worth it.
A big w00t for 36ers, though!
