My Felt Z90 came with cross levers. I like them for commuting (and in general), but mostly use them at slow speeds. I bought a new Surly Long Haul trucker, and decided I'd pull a cross lever off the rear brake of the Z90, and put it on the front brake of the LHT. The levers are designated as right and left, but the only difference as far as I can tell is aesthetic, not functional. Any potential problems using the right brake on the left side that I am overlooking? I've pulled it off the Felt, but haven't put it on the LHT yet.
