I ordered the front 15T sprocket from chainsandsprockets.co.uk. I went with the rubber cushioned JTF1370. JT don't do a 42T rear as far as I can tell so I bought an Afam 42T from UKRaceSupport.com. A little pricey, especially the delivery. Rear sprockets for the SC82 are the same as for the SC77.
thanks guys i ordered mine today through a local bike shop,i got the front cushioned one and the rear is coming from italy its a mix of steel and alloy,should be in ten days,have you got any idea where or who sells stomp {icon} grip tank grips apart from the USA
