I was just sitting on my XTR in the garage wishing my legs were longer (!) and started bouncing the front of the bike, which I've only had a fortnight. I noticed that there's a clunk from the forks in the middle of the compression stroke. It's not a bang like bottoming out, and the forks do continue to compress, but there's an obvious clunk. Is this normal? I'm sure I've not noticed it on previous bikes...
