hi there again. 2 people are watching this thread, me and my dad... i work nights. its actually a 6 gear freewheel gearset, not sure if that makes any difference. Telford a bit far TBH, im 90% sure i can fix it just need the parts, ive found a site that sells the electronic components for my bike but not the 6 - speed freewheel gearset.By sprocket, do you mean a 7-speed freewheel gearset? Perhaps if you show us a photo of what you have we can advise better.
