• Anyone able to give some advice on a chain stay u brake? I'm going insane. This old MBK frame needs one, but it's a mountain bike so put some fairly wide tyres on, I have a dia compe hombre brake fitted - the caliper arms touch when the pads contact the rim (already had to find some thick pads to get them close enough to contact) - it also seems like the wheel is about 5mm off centre - Most modern chainstay u brakes seem to have very narrow clearances.. Am I wasting my time trying to get this working? (I have re-organised the washers, realised I've taken the first two photos while messing about)

  • How much can you move it back on the drop out if it's semi horizontal?

    If it's a vertical, then going smaller tyres will be your only option.
