Popped into the office today to pick up a few goodies, and had a dig in the shed of dread (a big locker in my office that's threatening to collapse under the wieght of bicycle parts) for some 165mm shocks...
Here's what I have;
A fox coil shock with rebound adjust. Never ridden it myself but it appears sound. The powder coat is crumbling off of the spring in places, but otherwise the shock work appears to function as intended. No leaks, no squelching noises.
A fox float R air shock with rebound adjust. Holds Air, is in good condition, doesn't squelch.
a fox float RL with rebound adjust and lockout. As above, it appears to be in good order, and is holding air after a year in the shed of dread.
These shocks are all being replaced on my PRST-4's by more up to date models with platform damping like the RP23's, or if I can find them, the newer CTD shocks from Fox. This is easier and more expensively said then done though, the market for barely used recent shocks seems to be rather limited
Prices? Lord knows, I'm not going to give them away, but nor am I going to be make myself the subject of the "Profiteering" debate currently running, since these shocks were attached at one point to a frame I bought from a member here. But make a sensible offer that'll contribute to their replacements and I'll be happy to help out a fellow Retrobiker in need.
