HI, DONT KNOW IF ANYGOOD TO YOU,BUT HAVE UBRAKE COMPLETE FROM A 90S GT BRAVADO. IF I REMEMBER CORRECTLY ITS A MT/BT 63 SHIMANO WHICH EQUATES TO DX/XT QUALITY,IM SURE IT WILL CLEANUP WELL
have BMX U brake cheapy but works good, or in a while i may have an Shimano U brake in like bostin condition, if the evil buggers nake me split the bike, might be too ealry a u brake for your purposes though, let me know,
from experience and if you dont really care, BMX u brakes IMO are bettter,sipmpler easier to service lighter, erm what else, work just as well oh yeah they just better,IMO
