The rim for high-impact riding. The BA30 is a quality alloy rim designed to withstand a real beating. This is the rim for high-impact riding when the trails are rough and rugged. With an internal bracing structure, the BA30 has torsional stiffness for directional control in demanding circumstances. The BA30 features a thick bead wall adjacent to the tire to resist impact deformation, with a wider, rounded top-edge to reduce sidewall cuts. The nipple/spoke bed is oriented to the spoke direction to reduce weakness caused by bend in the spoke at the nipple hole. The BA30 is made with premium alloy, extruded with an internal brace profile and carefully formed for consistent shape. It is then fusion welded and ground for a strong precise finish. Our fusion welding system leaves a perfect seamless joint that becomes the strongest section of the rim ensuring that your rim wont split if you impact at the seam. – Premium extruded alloy – Fusion welded seam-ground finish – Internal bracing profile – Impact resistant design – Tubeless Ready – 27.5: 570g – 29: 610g – 27.5″ ERD: 566mm – 29″ ERD: 604mm
