BBB Rollerboys SRAM Sealed Composite (BDP-05) Derailleur Pulleys

The BBB RollerBoys (BDP-05) are high-performance 11-tooth jockey wheels engineered to optimize the shifting efficiency of your drivetrain. Constructed from a specialized composite material provided by EMS Swiss, the 40% glass-fiber mixture ensures exceptional durability and stiffness for a longer service life compared to standard pulley wheels.

• Broad SRAM Compatibility: These pulley wheels are specifically designed to be compatible with a wide range of SRAM systems, including legacy 9.0/9.0SL models and modern Apex, Rival, Force, and RED groupsets. They also support X.7, X.9, X.0, and XX mountain bike derailleurs.

• Universal Bushing System: To ensure a precise fit across different shifting platforms, the set includes a complete package of bushings. This allow for easy installation and proper alignment within the derailleur cage, regardless of the specific generation of your SRAM drivetrain.

• Smooth Mechanical Operation: Utilizing a high-quality internal lubricant system and CrMo bearings, the RollerBoys reduce friction in the drivetrain. The result is crisper, more reliable gear transitions and a quieter ride under both road and trail conditions.
