Havent Used it on real mtb features yet, but Ive ran down some stairs and used it while climbing a hill and I have to say its working quite well, Really liking the Solo air too.
I Used it on some MTB Features and It works pretty well, Huge improvement from the Argyle. The only part I was pissed off about was that I lost the Rebound Knob on the first day.
oh, yeah. haha that happens to everyones RS, usually everyone takes the R knob off.. you can get a new one on crc for 20 bucks, or just use a small allen key
