changing gear spontaneously? I got a new bike on tuesday (Norco Ryde) and since I have had it, the chain keeps skipping gears (For example when I change from 4th to 3rd it goes to 2nd gear and misses out 3rd), and changing gear without me touching the gear changer. This is only happening for gears 3+4 I think. could it be that the 3rd and 4th sprocket are too close together? Or could it be something else, if so please explain.
