I am looking for some long reach road bike brakes. The 600s i have will not quite engage the brake surface. I would really like to stick with some retro calipers but at this point I just need something to stop my bike. i would be willing to trade or buy. An older triple would also be nice. 172.5 is what I normally ride.
