Chromag Phase 30 Rim



The PHASE30 mirrors our 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. Our 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.


Premium extruded alloy
We’ve chosen our alloy for a measured balance between compliance and durability. Not everyone does this but it makes a big difference, both in the lifespan and performance of the wheel.

Fusion welded-ground seam
We use a fusion weld process to join the seam which creates a joint stronger than any other section of the rim. The rim surface is ground for a seamless finish which is precise and consistent overall.

Robust beadwall edge
It adds a couple grams but its worth it. All of our rims feature a beadwall that is about double the width of most of our competitors. The outside edge has an extra large radius to reduce cuts from sidewall impacts.

Directionally oriented nipple bed
We’ve designed the rim bed with an angle to match the spoke direction. This reduced spoke bend at the nipple and the end of the threads, which is known to be a common breaking point at the spoke.
