The components inside your wheels matter more than most riders realize. Hubs, skewers, and bearings determine how freely your wheels spin, how precisely they engage under power, and how long they last before needing service. The RA Cycles collection covers the full spectrum — from complete hub upgrades to individual replacement bearings and spare parts for rebuilds.

257 products from brands including Chris King, CeramicSpeed, DT Swiss, Industry Nine, and Enduro Bearings. Complete hub assemblies sit alongside ceramic bearing upgrade kits for existing wheelsets, individual sealed cartridge bearings, and small parts like pawl springs and axle nuts. Prices run from $2.50 to $945.

Buying Guide: Hubs, Skewers & Bearings

Hub quality shows up in two ways: engagement and bearing longevity. Faster engagement — fewer degrees of rotation before the drivetrain catches — matters most in technical terrain and hard accelerations, where a delayed pickup costs momentum. Bearing quality affects both rolling resistance and service life; ceramic bearings reduce friction compared to standard steel, and coated ceramic variants improve durability further. Skewers and through-axles affect stiffness at the wheel-frame interface — a detail that becomes obvious once you’ve ridden a precision-machined axle against a basic one.

RA Cycles stocks hubs, bearings, and hub components across the full range. Chris King’s R45D is the flagship complete hub — machined in the USA with their Ring Drive engagement system — available in road and disc configurations around $700. CeramicSpeed ceramic wheel kits upgrade existing wheelsets with ceramic or ceramic-coated bearings, with fitments covering DT Swiss, Zipp, ENVE, Lightweight, and Bontrager hubs from $630 to $945. For individual bearing replacement, Enduro’s sealed cartridge range covers most common hub sizes from $7. Spare parts — DT Swiss Star Ratchet springs, Industry Nine pawl kits, Problem Solvers axle nuts — round out the collection from $2.50.
