The TSR is our single speed/1x chain ring built for our MR30 crank sets. The TSR got its name after the way we developed this chain ring. Combing a Tall, Short tooth shape in an alternating pattern with a narrow wide profile allowing for a tight hold on your chain so you don’t have to worry about drops as well providing a quiet and smooth ride. It comes in two different off sets 3mm and 0mm to optimize clearance and chain line. This direct mount chain ring is compatible with 8-12 speeds and comes in even sizes 28-48.

Available for backorder if we don’t have stock. Can take 2-6 weeks to come from the US of A, but worth the wait!
