Phase30 Rim


Lighter format / all mountain / trail riding

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.

Solid Rims

Phase 30 rims build up really nice, not the lightest but not the heaviest either. Certainly tough. Amazing for the price.


Honestly, these rims have been great over the past year I have owned them. Usually, I manage to go through 2-3 high-quality allow rims a season. Not these. They have only been trued once and are still holding strong. Definitely at the top of my list when looking at higher-quality alloy rims.

Great rims

Had these rims on my smuggler for 2 years All Mountain/the odd amateur enduro, Pemberton, Van Isle and Whistler bike park, only needed truing once. Lightish/strong/well made and Canadian... great rims!

Solid and trusted

Ive been using these rims for a few weeks now and have had 0 issues at all, immediately noticed my bike rolling and handling faster (may have been more due to my old rims/wheels). Have been running tubeless and choosing bad lines the whole time with no marks on them. Although it does make me wonder if they could be made slightly lighter.
