Avalanche Woodie rear shock with steel spring (500lbs) custom 8.75 x 2.50 (made to fit a Canfield The One frame and reduce the travel without lowering the BB height). It can be adjusted back to 8.75x2.75 without too may issues. This shock is pretty much brand new. It has been used only six times (I was given a new frame from a mate at Commencal, so the One was sold) and is IMHO the best shock on the market still. this was set up for a 100kg rider (no fat jokes please) but can be reset for your weight.
The only issue I had was trying to find a Ti Spring for it, but since selling the One frame I have found out that Kronos do Ti springs to fit the Avi shocks.
Happy to ship anywhere in the world as I still have the shipping box that Avalanche sent it to me in (and the two replacement stickers).
