Chromag Phase30 Front Wheel

The Phase30 mirrors the BA30 profile but in a lighter format that suits all mountain and trail riding conditions.

This is a high quality alloy rim that is tougher than most with added protection at the bead-walls for impact resistance and reduced 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 Phase30 is made with premium alloy, extruded and carefully formed for consistent shape. It is then fusion welded and ground for a strong precise finish. The fusion welding system leaves a perfect seamless joint that becomes the strongest section of the rim ensuring that your rim won't split at the seam if you have an impact there.

The rims are laced to the new R4 hub. The R4 is designed to be a solid, reliable hub with a durable axle assembly and robust set of bearings.

Chromag opted for a Chromoly steel axle for stiffness and longevity. Using steel allows a smaller diameter axle which in turn gives more room to use larger, sealed bearings (USA made enduro bearings).
