I bought a Tektro 857AL V-brake to mount on my 29" using the method described in this thread. The arms are spec’d at 110mm and looking at them they seemed like they might be long enough to work with my 24x3 Berm Master. I mounted them on that wheel for kicks and they fit. The arms on this brake appear to be long enough to clear any tire that will fit in the Nimbus 24" MUni frame.
