I have a 1984 Univega MTB with a brake problem. I can squeeze the rear brakes for all I'm worth and still pedal the bike without too much effort. The front brakes work, but don't work great. I have have VO brake shoes with a little over 100 miles on them, so I don't think that's that problem. These Dia Compe brakes do not have an adjuster for the straddle wire, so I can't get the mechanical advantage up to where I'd like it.
I plan to replace the brakes, and am thinking I might as well put something pretty adjustable on it since this bike could become a 650b conversion down the line (it's 559 now). Does anyone have any thoughts or recommendations about the following brakes, or other suggestions?
