I ended up ordering an OE spec gold DID chain and sprocket set from Snells this afternoon, using the 10% DSC discount. Snells and OnyerBike both have over a months workshop waiting list, so I'll take it to a local bike shop, which is cheaper anyway. Needs to be done soon as I don't want any probs at Brands Indy later this month. All in all saved about £50 worth of beer tokens!

Matt
