When I pedal I get a creaking from the rear end of my road bike which isn't related to cadence. I think I've narrowed it down to my spokes as it sounds like the noise made when you squeeze together two that cross.
I have no loose spokes and my wheel is (fairly) true. I thought about tightening them all a quarter turn but then thought again as I have have no dishing tool to check the results (rear wheel therefore different spoke tension etc.).
Have I correctly diagnosed the problem and can anybody help please?
Also, is it common for spokes to come loose from their nipples as it happens occasionally to mine. In my weel's defense though, the roads round where I live are fairly crap and pot-hole ridden.
