Got a set of 2step airs on my ex demo nomad (09 model).Everything still works fine with the fork apart from this knocking sound.I'm guessing it's the bushes(sp).Will they be ok or sould i take them back to the LBS?.

Knocking on the return stroke?

i had this with my 08 2-step Lyriks….

was aware of it when they were new but it then stopped. so did the 2-step function. not sure if that had anything to do with it, but they're at the menders now.

should get them back in two/three weeks….

Yes,on the return stroke

I don't know if it's anyhelp but I had this problem with a new set of revelations. It was when I wound them down using the U-turn. Apparently it is normal. I sent them back under warranty to be looked at.

I have no idea if this would be the case for Lyriks.

HAve a look on the TFT site as there is something about knocking RS forks in the FAQ.
