Well been running the m4 evos all summer and Im quite impressed. I ride in southeastern Wyoming, and m4s have plenty of power for my stumpy. I ran the old X2s however they lacked the power I needed and felt I was always on the brakes. With the m4s I can just use 1 finger for steep decents.
On the rear however I did start out with a 160 rotor. Did any of you guys find a 160 rotor under powered? Feels like I was always on the brakes and burning through pads, and recently upgraded to a 183. Way better for my style of riding. Im about 200lbs without camelback and gear. One minor gripe is they arent as quite as my old x2s.
