anyone know where to get the lowest-priced Raceface square-tapered bottom brackets?
Small, hidden bike shops that may have some NOS.
Or E-Bay. Race Face isn't making 'em anymore, and thus hard to find.
Options are out there - UN-73 (XT Level Shimano), Interloc, Phil Wood ($$$$ but good), and SKF are all out there. There may be one or two others, but that's a working list to start with.
From one flat land to another.
Advocate as if your ride depends on it...
