So I've switched from a 6" TPC+ dual crown down to a more reasonable Pike426 Air U-Turn for my hardtail. I've had a few rides on the Pike and like it so far. I've mostly been using it in the 110mm setting and I noticed clicking or knocking sound at the very beginning of the stroke. The sound goes away if I move up to 120mm or 140mm of travel which I figure is weird. If it were a bushing problem I figure that knock should always be there, regardless of the travel setting .. right? The headset feels fine at each of the bottom and the top of the headset, and the sound is definately coming from the fork and not the headset. I weigh 185lbs on a good day and have 150psi in each of the positive and negative air chambers. I googled the hell out of the Pike and it looks like no one is having this issue except me.
