I have an O2 and a Glyde RL on single-pivot 5-inch frames and am very pleased with them.
O2 is a very simple shock with only air-pressure variable.
Glyde RL has a 300lb/inch spring with preload and rebound-to-lockout variables.
No hesitation to get more, escpecially when they come up for a song on ebay.
Well I’ve had mine a whole 3 months of riding in the Lakes and its holding up fine. In a fit and forget kind a way it gets on and does the job. Perhaps I got lucky on the set up as there ain’t a lot to adjust on my Pitch.
Got an O2rc on my FSR, been on for 18 months with no probs really. Adjustable damping seems to work well. I knackered the thread on the air valve (my fault) and got a replacement from the x-Fusion importers/dealers. They were pretty helpful and can handle all servicing if necessary.
