Here we have a single crown Fox Vanilla Front fork, they are 125 model rl and can be set up for 80mm, 100mm or 125mm travel.
I had them on a 650b project I built but now are surplus to requirements. Fox are the only forks off the shelf that take a 650b wheel & tyre.

The steer is a 1 &1/8" and is cut to 200mm with a star nut fitted.
The lockout doesn't seam to work although it has in the passed but I never tended to use it, I've been told that if you pump the fork on the bike it will free the lock out but fid that hard to when it's not on the bike.
They work fine last time i used them & see no reason for them to continue.
The stanchions are fine with no rubbing or wear marks, they don't leak, the lowers have some marks from cable rub & where the brake disc caught. there is also a ding on the lower by the brake fitting but none of this effects the performance.
