RISK RA126 11T Ceramic Bearing Rear Derailleur Pulley Wheel for MTB Road Bike

The RISK RA126 11T Ceramic Bearing Pulley Wheel is designed for smooth, efficient, and reliable shifting performance on mountain bikes and road bikes.

Equipped with a ceramic bearing, the pulley wheel delivers smooth rotation, low friction, and quiet operation. Its hollowed-out lightweight design helps reduce weight while maintaining strength. The included adapter sleeves allow compatibility with 4 mm, 5 mm, and 6 mm mounting shafts, making it suitable for a wide range of rear derailleurs.
