As part of my ongoing refresh of my gen1, I am replacing the chain and sprockets. Its actually the first time I have had the sprocket cover off since buyingthe bike in 08 and was expecting some force to remove the sprocket nut , but it was almost loose ! The copper tab washer was in place, and the nut came off very easily.I was quite surprised to see a lot of wear from the sprocket , as the rear is almost like new ( 37 k miles !)...but the front is u/s...and the teeth very thin indeed, and visibly hooked .The chain itself is not totally worn out , but it was a bit of a shock to see how bad the sprocket was. Food for thought as if it had got any worse, possibly the chain could have jammed, should one or more teeth collapse.... :eek
