Twenty Rear Sprocket Steel Black

Lasts up to three times as long as an aluminum sprocket!
Twenty now proudly presents the lightest steel sprocket on the market!
The tooth profile reduces chain vibration/slap which provides smoother acceleration by evenly distributing power to the rear wheel.
The sprockets are laser cut in order to reduce the amount of material used without reducing the strength or stiffness.
They also have incredibly tight tolerances for perfect concentricity and fit.
The surface is painted black for excellent protection against all types of corrosion. This also gives a fresh finish.
Do not forget to buy new sprocket bolts.
