Phase30 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. This rim is made with premium alloy, extruded and carefully formed for consistent shape. It is then fusion welded and ground for a strong precise finish. Chromag's 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 brand's new R4 hub. The R4 is designed to be a solid, reliable hub with a durable axle assembly and robust set of bearings. Chromag is using a tried and tested 4-pawl arrangement with 36 points of simultaneous engagement.
