The BA30 is a quality alloy wheel designed to withstand a real beating, ready 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. - BA30 rim features a thick bead wall adjacent 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 - Made with premium alloy, extruded with an internal brace profile, and carefully formed for consistent shape - The rim is fusion welded and ground for a strong precise finish, leaving a perfect seamless joint that becomes the strongest section of the rim, ensuring that your rim won’t split if you impact at the seam - Laced to Chromag’s R4 hub, designed to be a solid, reliable hub with a durable axle assembly and robust set of bearings and Chromoly steel axle for stiffness and longevity
