OK, I just hung the phone up with Custom Axis directly, I know there is much debate over this at the moment, so here is the deal:
They WILL build a cannondale rear shock.
They WILL sell you a cannondale rear shock.
However, they feel that with the leverage rate of the swingarm, that with a heavy/fast rder that the shock will not last.
The shock I checked on was for a 175lb "B" level mx and they said "no problem doing that one" .
So, for anyone wanting a custom axis rear shock, if you weigh under 200lb (or are slow :w: hehe) call me and I can get you a shock shipped right to the door.
