Have not been used this season, have been used very sparingly entire life. Not exactly sure of the travel but the sanctions are 120mm long.These hold air perfectly and when I put weight on them they feel smooth yet firm. Dual air chambers on top of each leg and one on bottom.
Other leg has rebound adjustment. You need a high pressure fork pump to adjust these, found just about everywhere. The air pressure for your body weight is right on the leg so they are easy to adjust.I would suggest a full rebuild before any real serious trail riding. But it's up to you, they feel pretty sweet as is. 8 5/8 or 22cm length steerer tube, nice long length to work with. The only weigh 2 pounds 13 ounces!!! Even with that long of a steerer. Could use some new decals if one wishes. Remove old decals with 70% rubbing alcohol. That tears up finishes and that would suck! Should fit just about any bike out there, you may need to cut it down a bit for small size bikes.
Orks with both disc or v-brakes, if your going to run v-brakes you will need to install bosses(titanium would be best). Stanchions are in excellent condition with no scratches, there is what looks to be some light oil staining on one leg? It doesn't effect performance and really isn't noticeable. Here's more info on shock, it's actually 80mm of travel sorry for any confusion. Actual fork travel may vary +/- 3 mm.
