Last week, at the end of a ride, I noticed a broken spoke on my rear wheel. I was unable to get to my usual bike shop so I put it in for repair at a well know bike shop asking them to check the wheel and tighten up any other spokes needing adjustment. Picked it up midweek but didnt inspect the work and went for a ride yesterday starting at Duckholes track. I was 10 minutes into the ride when disaster struck; i elected to change gear from middle to large ring which was followed by alarming noises.
