Ok. Chainring bolts all done up tight. Not quite sure how I can check for play in the BB? I think there might be some, I'm not sure though really. :-S
Don't know how I can check the pedals, but I have felt them and spun them, they seem to be fine to be honest - and the sound sounds like it is coming from the cranks or deeper down in the bike really. On both sides.
I have really basic simple pedals at the moment, just at the moment trying to choose between a few SPD jobbies. Will update my pedal thread after this actually! So yeah - not clipless at the moment.
Whereabouts are the cleat bolts? Sorry.
Doesn't stop when I stand - and I am 18.
Thanks for all the help everyone.
