I have a set of USE suspension forks, not sure if its the ones your after though?
There in fantastic condition, I bought them a few years ago off ebay as near new (used for 1 bike ride the previous owner assured me), put them on my Muddyfox and did about 5 miles with them at most!!! The wiper seals are still sticking alittle on initial travel, but very plush when going through their travel. They seem to loose are pressure after about two weeks, so will need a service, which Im sure the manual shows how to do which I have. I also have a lot of spares (elastomers and springs I think?) There is very very little in the way of wear, just a very very small nick in one of the decals that I can remember. They are great forks, but just dont suit my bike as I prefer the front to be alittle higher, so theyve been replaced by a set of pace rc36s. Are these what you would be looking for?
