Man, that was a tough request. I had to do some digging, but I finally found the original invoice from the on-line shop where I bought it. The invoice is dated October, 2004 and the Avid disc brake assembly was listed as BR7082. Not sure what that means - an Avid part number or the shop's in

Very good points, George. Question: what model/version of the BB7s are you using? Are they mountain or road? New or old? For the record, all my disc setups (all 3 have been BB7s, 1 or 2 mountain of the circa 2012 or so vintage; 2 road, one circa 2010, one 2016) have been installed on bikes with h

Patrick - I'd add one more item to your list. I've got a BB7 on the front of my Surly 1x1 and for years I had trouble with the pads rubbing the rotor, making noises while riding - just as Jan has pointed out as a potential shortcoming of discs. I tried everything; trued the rotor, changed the

It seems that mechanical discs need larger rotors than hydraulics, that is all. We tested a Jones with 200 mm rotors and mechanical (mtb) Shimano discs (XT, I recall), and they were very powerful, but a bit too grabby. All the bikes we've tested recently with 160 mm rotors (mostly TRP Spyre brakes

I use TRP Hy/Rds on my Foundry Auger, with TRP Pro compressionless housing. The Hy/Rds are worlds better than the BB7R's that I used previously, and almost as good as XT or Guide MTB hydraulic brakes. The secret (same as with any mechanical disc brake) is to keep the rotor really true so that you

At least from my experience the adaptors "kick out" production racks too much so you end up with them sitting too high and the rack slanting up. For a custom rack that is not a problem though. Clayton Scott SF, CA On Wednesday, January 11, 2017 at 5:21:32 PM UTC-8, René wrote: > I wonder why y

Good question. Cantis and centerpulls really need good setup. Most use an oversized brake cable as a straddle wire, which needs to be set to conform to the straddle cable hanger, otherwise, it takes the first lever travel just to straighten the straddle wire. There are better ways to set up straddl
