I've always been told that Cantilever brakes had the best mechanical advantage and thus were best equipped for loaded touring if properly adjusted. I recently ran into a guy touring the US on a LHT with his girlfriend. They both had LHTs. One had canti, the other V brakes. He swore up and down that he got better braking power with the V brake and it was much easier to adjust / deal with.
What would you do?
V brake or Canti?
I guess i should mention that the bike would be running drop down bars and Tektro brake levers.
