Description
The PHASE30 mirrors Chromag’s 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 Chromag’s new R4 hub. The R4 is designed to be a solid, reliable hub with a durable axle assembly and robust set of bearings. They’re using 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.
They opted for a Chromoly steel axle for stiffness and longevity. Using steel allows a smaller diameter axle which in turn gives us more room to use larger, sealed bearings (using USA made enduro bearings). The rear axle assembly uses thread-on end caps which are easy to service and resist compression from the frames axle (they don’t fall off during trailside repairs either!).
