Today I was riding in the hills, and was gently going up-hill in 3rd gear or so and PING! one of my rear spokes broke off at the hub end.... is this normal? I had done about 50km of riding by this point and had gone over some rough patches that might have bent the rear rim, although the bend in it could be from after i broke a spoke....any ideas? i have 32 spoke wheels with Alex 22A rims.
