Origin8 Ceramic Bearing Pulley Wheel Set – 7/8/9/10/11 Speed – Fits Shimano, SRAM, Campagnolo

Upgrade your rear derailleur with these Origin8 ceramic bearing pulley wheels.

They fit 7, 8, 9, 10, and 11-speed drivetrains—compatible with Shimano, SRAM, and Campagnolo.

Ceramic bearings spin smoother and last longer than steel, reducing friction and maybe shifting a bit crisper.

Set includes both upper and lower pulleys.

Item width 5.5 inches, weight 0.09 lb (so, very light).

1-year warranty.

California Prop 65 warning applies (standard for bike parts).
