Chromag BA30 27.5″ Rear Wheel R4 6 Bolt

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 more comprehensive, rounded top edge to reduce sidewall cuts. The nipple/spoke bed is oriented to the spoke direction to reduce weakness caused by a 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 a 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 most robust section of the rim ensuring that your rim won’t split if you impact at the seam.
