The other day I replaced my stock tires on my trek 2100 which were bontrager race lite 700x25c to Michelin Pro Race 700x23c and My first ride on the new tires on a 26 mile route that I ride regularly turned out to be my fastest time to date on that route here's the numbers on my old tires: Avg speed 15,max speed 35.3, time-1.44.11 then on my new tires first ride : Avg speed-16.8mph,max speed-36.5mph,time-1.33.49 shaving nearly 11 minutes off my avg time!!!! So I am in awe and refuse to believe that tires can make that big a difference so I go for a 26 mile ride today same route similar weather avg speed-16.5mph, max speed-36mph,time-1.35.33 nearly identical to my previous days ride it's gotta be the tires. I just thought that was interesting and figured I would share it.
