I bought a Salsa a la Carte steel hardtail frame last week and I'm thinking about going back to V brakes. My current bike has Hayes MX2 mechanical discs. They are actually pretty good. They have been trouble free, but just don't have the "bite" of V's. Had a set of Hayes hydraulic's way back in 2000 and they sucked bad. Been reading up, and it looks like people still have problems with hydraulics. Leaking, pad rub, bleeding, ect. Was looking hard at the Avid Juicy 7's. If I went with V brakes it would save me money. Not to mention they are lighter. I can use my almost new XT shifter/brake levers and I've had a set of XT V's collecting dust for a few years. And I can get a good deal on a wheelset with non disc Chris King hubs. Can anyone give me a reason to keep considering discs?
