Jon Alty Posted November 27, 2012 Report Share Posted November 27, 2012 So I've brought my Dad's Trek Madone 5.2 up to uni to cycle around (live about 30 mins from city centre) and generally enjoy cycling for fitness. I usually listen to my iPod when cycling, so never really noticed it before, but I did a 100mile charity cycle recently and did'nt take my headphones, and noticed whenever going over rough surfaces, the bike was really rattly, as if there were coins or something inside the frame? I removed my saddle bag to make sure it wasnt that, and the noise is still there. The noise is only noitceable on rough surfaces, not when the road is smooth. Anyone know what could cause this?

N.Wood Posted November 27, 2012 Report Share Posted November 27, 2012 Cables against frame, swarf / gravel in tubes, chain, loose headset, loose wheel cones, um... A load of different parts. Quote Link to comment Share on other sites More sharing options...
Revolver Posted November 27, 2012 Report Share Posted November 27, 2012 Gradually take it to pieces and shake each one, you'll find it eventually. If not, maybe it is something that's loose, that when you reassemble the bike, won't be loose any more. Quote Link to comment Share on other sites More sharing options...
Blake Posted November 27, 2012 Report Share Posted November 27, 2012 have you got a bottle cage? They've always rattled for me Quote Link to comment Share on other sites More sharing options...
Jon Alty Posted November 27, 2012 Author Report Share Posted November 27, 2012 You see this is the thing, if I pick the bike up and give it a shake, there's no rattle to be heard. It feels around the BB area, maybe I'll just strip it down and reassemble and see if that does the trick. Quote Link to comment Share on other sites More sharing options...
Blake Posted November 28, 2012 Report Share Posted November 28, 2012 bearings could be worn and loose? Quote Link to comment Share on other sites More sharing options...
Jon Alty Posted November 28, 2012 Author Report Share Posted November 28, 2012 BB bearings you mean? I'll check! Quote Link to comment Share on other sites More sharing options...
Blake Posted November 28, 2012 Report Share Posted November 28, 2012 yeah, or like the axle has got play and wobbles a bit, happens to old bikes a lot. Quote Link to comment Share on other sites More sharing options...
