I ditched the Avid cantilever front brakes on my tourer for a set of Cane Creek Direct Curve brakes
http://www.canecreek.com/component-o...direct-curve-5. They don't squeal as much as any of the cantis I've tried, they stay adjusted longer, and they seem to stop the bike a lot faster. I installed the Drop V levers
http://www.canecreek.com/component-other?product=drop-v because I don't like the idea of a travel agent or any other gimmicks. I use bar-con shift levers, which simplifies he job of picking out a brake lever.
