Product Info

"Buy once, cry once" is a little too heavy on the tears, if you're talking about the Chromag BA30 27.5" Wheels. These tough aluminum rims are made to slap on a bike and start pedaling. Without a map, even. They're 30mm wide, making them very versatile and able to fit tires up to 2.8" with no problems. Light enough for XC riding and resilient enough for some gnar, they're great for what's commonly known as "mountain biking!"

Product Details


Tubeless Ready, Taped, Valves Included


30mm Internal Width

BA30This 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 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.



Front Hub

Chromag R4

Rear Hub

Chromag R4The R4 is designed to be a solid, reliable hub with a durable axle assembly and robust set of bearings. These use a tried and tested 4-pawl arrangement with 36 points of simultaneous engagement. What sets it apart is the large radius that the pawls are positioned on, reducing leverage at the point of engagement.
