August 18, 20188 yr https://bvm-moto.co.uk/index.php?route=product/product&product_id=2193 I just bought an 11 tooth from BVM. Superfast delivery, and as I was a bit nervous about delivery in time for this weekend they phoned me up to confirm it was just despatched. Note that 11 tooth is standard. Going down to 10 tooth will make a 9% change in gear ratio unless to change the rear as well. The 10 tooth will also accelerate chain and sprocket wear.
August 19, 20188 yr Author What size rear sprocket are you using? Mine is 12 / 52 runs too quick for me.
August 19, 20188 yr I'm using 11/53, which is the standard gearing according to the user manual. Your gearing is 10% taller. Sometimes I think mine is too low geared, and other times it feels too high, so I reckon it's really about right.
