Thanks but no thanks. I think I'll pass.
Back from my ride this morning. Started well, then it went decidedly darker the longer it went on. Eventually managed 8 miles before the rain started. Now relaxing with a cup of coffee. Hope everyone enjoys they're ride today.

, after that see if it happens per revolution of the pedals if at the same part of the rotation, try tightening the crank bolts mine come a little undone (not loose) but enough to make the crank maybe creak a little, an noises on bike can be amplified through the frame. Other possible causes saddle, headset, pedals it is likely to be one of these.
