FS/Trade: Avid Elixir 1 and Avid Elixir 5, disc brake sets

These are take off brakes from mountain bikes, two complete sets, no rotors, no IS adaptors.

The Elixir 1 are fresh, maybe ten rides.
The Elixir 5 are in very good condition, one season of use, comes with new pads.

I’d like to trade each brake set for a comparable set of BB7 with Speedial levers.

Alternatively I’d consider offers on the brakes. These are very lightweight brakes, powerful, easy to adjust, would make great uni brakes, hydraulic hose is easy to shorten.
