I purchased this bike a little over a year ago and so far it's been a great ride. The only issue I'm having is with the Fox Float RLC 100 fork. It's making a knocking sound at the top of the travel that sounds like my headset or front tire are loose which niether of them are. It's most noticable when climbing and the front tire is un-weighted. Other than that knock, the fork runs smooth, but it sure doesn't sound right. The LBS I took it to didn't come up with anything. Anyone else had this issue??
