Chromag Ally Rear Wheel

The Ally is Chromag's latest rim offering and is the workhorse of the fleet. Building off the BA30 and Phase30 design, the Ally offers the same robust beadwall and 30 mm bed but in a pinned construction helping to keep the cost down.

The Ally shares the same cavity construction as the Phase30, with symmetric nipple drilling, designed to get you rolling on a budget.

The 26" rim is paired with Chromag's D1 hub when the 27.5" and 29" are laced to the R4 hub. The R4 is designed to be a solid, reliable hub with a durable axle assembly and robust set of bearings. Chromag are 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.

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). 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!). R4 rear hubs are available with XD or HG driver bodies.
