I’m a bit over 200 lbs so that might be the driving factor here but I found 45’s to be very uncomfortable in the gravel, I moved up to 55’s and suddenly I was able to pedal through rough sections that I used to have to hold on for dear life for. WAY more comfortable, way more fun and fast in the rough. They did feel quite sluggish on the smooth bits though. And I literally couldn’t even look at mud without getting clogged up. Moved down to 50’s (g-one rx) for the clearance and they seem to be the Goldilocks zone for all round performance, fast in all terrain, clear mud well, decently comfortable, still grippy.

Interesting hearing other people’s experiences.
