>>1323015my main road is absolutely horrible and scary with a with a road bike on 25c @80psi at 50km/h and at at extreme sun angles can be deadly. Potholes are deathtraps. I have been on the edge of aero bars and and had the whole bar/stem rotate under heavy impacts. It makes me nervous.
Took my FS mountain bike with 26 x 2.00 slicks and rode the same the same road at the same time and didn't even bat an an eye.
Do you want to be 50% more comfy ? or 50% more fast ? Thats how i calculate it.
