Speed wobbles on a carbon fork?
About a year ago I was coasting down a hill (20 mph) without my hands on the bars and my fork started wobbling a disturbing amount, it looked like it was about to snap. I grabbed the bars and started pedaling again, all was fine.
That incident was the only time I have gotten any sort of wobble/play out of the fork until last night. I was on a longer descent, spinning away on a higher gear when my left foot unclipped. At this point I was riding at ~32 or so. The second my foot unclipped my fork started wobbling violently again. My weight was displaced a bit when my foot unclipped, when the fork took its first wobble the whole bike got thrown to the right.
I was able to straighten out, that said, what's going on? I have been over 40 mph on her without any problems. I assumed it was just when I was riding hands free, but, even then it seemed a bit out of the ordinary, no?
