Description
JT Sprockets – the World’s No.1 market of aftermarket sprockets.
JT Rear Sprockets use super hard ultra durable high-carbon C49 steel. No other rear sprocket is made from this material. Most use weaker C45 steel. Spending $5 or $10 more for a set of quality JT Sprockets, in the big picture, is money well spent, giving you or your customer up to 2 to 3 times the life of your sprockets and chain.
