somes just prefer not to touch their bikes is ok. is why they make 'spensive pulleys for you guys.
changing gears seems too big a project for most folks that are skared of the inards of their motors. is not a difficult job and can be done in an evening. more than changing the gears or the bike character, this kinda work changes you. 'tis worth it. ponchout

Dear Ponch,
I did the math on the front pulley change 32 to 33 ,,,,it came out to a 3.1% decrease in RPM. The Trans gear change from 42/50 to euro 44/48 revealed 8.43% decrease in RPM!!!!!!!!!! I'm planning on doing both for a total of 11.53% decrease.
