    Caffeine 3 Rotor question

    I notice that it's spec.'d with 180 front/160 rear. Is the rear rotor size due to a limitation of the frame? I'd like to run a 180 back there as well.
    Also, the streets are full of horizontal dropouts...

    Seems to be 160mm front and rear... but, usually, a bigger rotor is not as necessary on the back than on the front. Someone could confirm it but I'm pretty sure you could put 180mm rotors if you want.

    I test rode last year's caffiene 29 which had 160's F&R on BB5's and it was a bit under-braked which seemed to be a pretty common complaint so apparently the spec got updated to a 180 front rotor. My Caffiene 3 arrives in the next week or so and I've goe for BB7's with 160's front and rear. We'll see how that goes...

    We were talking bout the F29 Caffeine 3? I see then... I gotta agree that BB5 are not the most powerful. The bike is speced with a 185mm front...

    FWIW I won't be running the stock BB5 brakes, and several years of experience has convinced me that 160mm rotors simply aren't adequate for someone my size regardless of the calipers being used.

    Bump. I'm still trying to find out if the Caffiene 3 frame will accept a rotor larger than 160mm in the rear.
