The Bontrager Rapid Drive 108 Free Hub Pawls are essential replacement or upgrade components designed for cyclists using Bontrager Rapid Drive hub systems. These pawls are ideal for riders looking to maintain or tune their hub engagement for better power transfer on the trail. A key benefit is the modular engagement capability, allowing for either 54-tooth or 108-tooth engagement, though users should be aware that compatible springs are not included and must be purchased separately.

No, the springs are sold separately.
These specific pawls are designed for 148mm Boost spacing, though they may fit other Rapid Drive 108 shells depending on the specific wheel model.
Using 3 pawls results in 54-tooth engagement, while using 6 pawls results in 108-tooth engagement.
It is recommended to inspect and clean your freehub every 50-100 riding hours, or more frequently in muddy or wet conditions.
Use only a light, freehub-specific oil or grease approved by Bontrager; avoid thick automotive or bearing greases.
Check that the springs are seated correctly and that you are using the correct light-viscosity lubricant.
You may have used too much or too thick of a grease; clean the assembly and re-apply a thinner pawl-specific lubricant.
Ensure all pawls are intact and that the engagement teeth inside the hub shell are not damaged or rounded.
To install these pawls, first remove the freehub body from your 148mm Boost rear hub. Clean the pawl pockets thoroughly with a degreaser to remove old, contaminated grease. Apply a light, specific freehub pawl lubricant—avoid heavy greases that can cause the pawls to stick. Insert your separately purchased springs into the seats, then carefully align the new pawls. Before reassembly, check that all pawls snap back freely when depressed. Ensure the freehub seal is clean and properly seated to prevent dirt ingress, which is the primary cause of pawl failure.
