hay look, a ****, grab it before it gets away. No sorry, it's not mine, I have no more to give.
My fast bike (a Forme longcliffe) runs calipers.
My winter bike (A coyote, something) runs discs.
My pink monster (GT Average lance) runs discs.
My carlton GP, thats calipers
My inbred, oh no, that's disc.
**** it, ride what the hell you want, neither technology is going anywhere anytime soon. from the point of view of longevity, discs win, you ain't replacing a rim when the braking surface is done, from a rose tinted, rim brakes are great. As long as they stop you, is it really (REALLY) worth the fuss.
Ride it, enjoy it, occasionally clean it and most of all **** IT.
