[Closed] Anyone else still on Avid BB7's?

The Avid multi-adjust washers are fabulous - especially if you make your own frames and the disc mount might not be 100% parallel to the dropout.....

I'm sure Avid made the Elixirs so unreliable just because they never got any aftersales revenue from BB7s 🙂

Have you "manipulated" the ali tubing to fit the frame and just have standard outers from the lever to take up steering slack/flex? What do you use at the join?

Edit this tubing?

Edit 2, looks like you're using cable adjusters at the join, but whats going on between the adjuster and the first cable stop on this pic?

[i]Edit 1:[/i] That looks like the tubing. I've got a "man in a shed with hand tools" approach to my bodges, so there's nothing very sophisticated about what I do, so basically if it looks like the right diameter for outer, it'll do. 🙂

[i]Edit 2:[/i] I'm using a flexible V-brake part there

The type I use has an adjuster on it. I also have used stepped ferrules for the intersection of the cables, so in some cases I have used about 5mm length of larger diameter tubing to form a collar on the 6mm tubing (also available from B&Q, just pick the size that slides over the one you use as outer)

The tubing is easily manipulated just using your hands, mainly your thumbs. Just do it gently because it work hardens so you can't unbend mistakes gracefully. It's cheap enough to make mistakes though. I cut the tube with a very fine hacksaw and use a countersink piece in a hand driver to tidy up the inside of the end.

If your rear wheel is on sliders or track ends, you need to have a short length of standard outer leading up to the disk to allow for wheel adjustment as seen here:

Most of my bikes have them as long as you're not doing and fast techy down hill they are perfect

I've got a set of unused Avid Pit Stop Full Metal jacket if anyone wants it - unsure of the going rate these days.

Really like to the mountain versions, just fit and forget, but found over 3 years the road versions a constant fiddling, fettling, faff.

Just swapped the road BB7s for TRPs, and despite some initial set-up issues they seem really good. Also hoping they won't be such a problem when fully loaded for touring, the wide profile of the BB7s were a bit of a problem with racks and panniers.

That's because road levers flex, so by the time you have used up the flex, there's not much cable pull left to operate the brake.

You usually compensate for this by setting the pads close to the disk, so the slightest irregularity in the disk causes rub, hence constant adjustment.

A more rigid outer helps make up for the deficiencies of the lever.
