Thanks everyone for the replies,
Onzadog – thanks I will give that a go, had no idea you could run it without the damper, but would be interesting to see if its still slow.
The thought had occurred to me to get those PUSH springs, I’ve heard on that other thread that they’re excellent, its just at what point do you stop chucking money at something really. TBH I have BOS Devilles on a 26″ bike and am sort of kicking myself now for not just getting another set. Performance of the BOS damper is first class, its just I’d hoped that the 36 chassis combined with the Avy damper would be awesome.
I’m about 82kg and the cartridge is brand new. As you’ve all said, Avvy cartridges have a great reputation so its unlikely to be that. This thread does give me some ideas though, so thank you.
Oh actually 1 thing to say having gone out today. I tried that burping technique whereby you pop a zip tie under the seal. After this they did seem a bit better, but don’t blow you away. Plus its warmer today, I don’t know if the Fox air spring gets affected by the cold?
