Sparky
Race Dog
Took off my back wheel today and noticed that the sprocket is near to it's end. Also checked the front and that looks brand new, almost no wear at all. The chain still looks good as well. The set only has 10000km on it.
Do I have to replace the whole set, or can I just replace the back?
