A limited edition version of our most popular carbon road disk wheelset, our 40mm Mahi Mahi rim is now available in a semi-gloss finish with a new decal design in 2 colour options; grey and light blue.

The 40mm deep disk-specific rim design allows for optimised aerodynamics while the low weight is an important part of the lively, responsive feel and streamlined performance of these wheels in all weather conditions. As with all our wheels they are handbuilt by us in our York workshop for perfect build quality every time with a choice of hub colours and spoke nipples for the perfect fit with your bike. As standard we build these wheels onto our lightest, most popular hub choice, the centerlock disk straight-pull version. Please contact us if you would like these wheels built onto any of our other hubs.

This wheelset is built to order. We hold most parts in stock and build them after you have ordered. The build time is advertised on the front page on under the title.

  • All wheels have tubeless tape applied.
  • There are no additional parts provided.

build quality

During the building process all components are bedded in, stretched, and tensioned repeatedly so the wheels won’t go out of true. We inspect, check and finish every wheel with equal care.

handbuilt in the UK
