Hi, Neal
I contacted B&CExpress and they answeed: "None of our suppliers list a 16 tooth front sprocket for your bike, however we can supplier you with a Renthal 266-520-40HA (40 Tooth) rear sprocket."
intobikes.co.uk don't seem to carry 16T either.
I'll keep looking around, I still have some time until my pistons arrive.
