Got a friend who has a singlespeed, and where the existing V-brakes on it very cheap -- they stop OK, but barely so. Modulation is pretty sucky even when adjusting the cables.
Upgrading the bike to discs is out of the question, just due to cost.
He wants to get something with top-notch stopping power, so he is looking at upgrading what he has on there to XTR BR-M970s, Shimano's best V-brakes.
I'm telling him consider Avid SD Ultimate or something along those lines and save the $10-$50.
Is the price premium for the '07 XTR stoppers worth it?
