I've just had my chain and sprockets replaced this morning. I spent yesterday sourcing parts, cos my local bike shop didn't have my sprockets in stock and I wanted them replaced this morning. Anyway, I ended up saving about $40 buying the chain n sprockets from Johnny O in at Yamaha city, can't thank you enough, top service and price. When I take the parts into my local bike shop this morning for fitting, I mentioned how in future they will get the labour but not the sale on spares, if I can save that much going elsewhere. The came back with lame excuses about DID chains not being a good brand along with crap about city stores being cheaper cos thats the only way they can get customers, a day trip to the city, tolls, parking and lunch make it cheaper in the long run to buy local, what a load of hooey. Anyway, are DID chains crap, and if so, what should I have got and why?
