SD-X BEARING
The hubs SD-X Sniper Evo are equipped with high-end SKF bearings, used here specifically as the external driver bearing.
Made from high-quality chrome steel (100Cr6 / AISI 52100) and fitted with precision-ground hardened steel balls, these bearings are designed to withstand high loads while maintaining low friction.
Their optimized internal geometry ensures smooth rotation of the driver, reliable engagement, and a long service life, even under the extreme stresses generated in BMX racing.
NOTE : For maximum performance, optimal reliability, and extended service life, SD strongly recommends the use of original SD-X specified wheel bearings.
