Seasoned professionals have not been able to eliminate all noises from my Avid BB7's . Luckily that was not my goal. I don't trust myself to work on my disc brakes but I had no choice anymore, when I switched to drop bars. The new Tektro levers were short pull only, and the BB7 calipers were long pull. I didn't want to spend for short pull calipers, so I got some close out inline Travel Agents. The drag from them was immense and the brakes wouldn't return. I had to rig up a DIY brake booster. It works fine but now no LBS will touch the brakes. There have been a LOT of posts here recently featuring disc brake fanaticism and IMO it is so misplaced. V or Cantilever brakes can offer performance equal to mechanical discs at 1/4 the price, and when properly adjusted, and the wheels true, are totally silent. The work on them can be done by anyone. Bicycles do not need brakes worthy of 600cc motorcycles. That is what is showing up on some of the high end downhill bikes these days. Really? Who am I. If someone wants to spend what many people spend buying a used car, just on brakes for a commuter bicycle, again, who am I. Its the notion that it must be that way that annoys me. Humanity did just fine before mechanical disc brakes made the concept feasible to implement in "affordable" consumer bicycles. I've owned the tandem with the BB7's since 2005. That bike only comes out to play in the summer and only when there is a group ride on at the Tandem Club. Our other tandem which is our car and is in near daily use taking the wife to the train station has V-brakes. My commuter singles, cantilevers. Folders, v-brakes. If disc brakes were really that much better, it would be criminal of me to continue riding all those other bikes until they were upgraded. FWIW.

P.S. I'm sure some of my bikes have had the same rims for 12 years!
