I am putting together a new Trek 520 that still has the original Avid V-brakes installed. I have a full fender and a Tubus Logo rack also on the rear. The Logo and the rear V-brake don't mix on the Trek 520 because the left top support arm on the Logo impedes the metal brake cable enclosure from clamping the left side of the V-brake to the rim, as it should.
Has anyone else had this problem and if so what kind of brake works best with a semi cluttered set up like this? Caliper, Cantilever?
