BBB RollerBoys 11-tooth black rollers

The BBB Cycling RollerBoys 11-tooth jockey wheels are designed to optimize the smoothness and precision of gear changes on road and mountain bikes. Made from an EMS Swiss composite material reinforced with 40% fiberglass, they offer excellent wear resistance while maintaining a low weight. This construction ensures reliable and long-lasting performance, even under intensive use.

The pulleys are equipped with low-friction, sealed ABEC-3 industrial bearings, ensuring smooth, quiet rotation and a long service life. Their design reduces energy loss in the drivetrain and improves overall pedaling efficiency. The kit is compatible with Shimano 9- and 10-speed drivetrains, MegaRange systems, and Campagnolo 11-speed groupsets.

The product comes as a pair of 11-tooth pulleys with a complete set of spacers, allowing for easy installation and broad compatibility with various derailleur systems. These pulleys provide a reliable solution for replacing or upgrading original components, while ensuring precise and stable drivetrain operation.
