Only been out on it a few times, and I seem to be experiencing a clicking noise when I "put the power down" and accelerate hard. It's just a one off "click" that I hear at the point which I press down hard but then nothing as I continue to pedal. I think its coming from the chainset, or BB. I've done the obvious thing and checked the tightness of the bolts but is there anything else that I should be investigating? The bike shop is in the Town centre and is a royal pain in the ass to get to, so if I can fix it myself it would be much better. Cheers.
