Our fastest road wheelset yet, named after one of the fastest fish in the ocean. Like the fast fish, the streamlined shape of our Mahi mahi wheelset cuts through the air for faster riding in races, chaingangs or just riding along.

Go aero with our super fast new carbon road wheelsets. Built for speed and strength these wheels will perform in all conditions including rain and wind.

Built around our lightweight jra hubs with 20 Sapim CX-Ray spokes front, 24 rear, the Mahi Mahi is normally available from stock in rim depths of 10mm increments – 35, 45 and 55mm (with others to order up to 80mm). The rims feature an ultra flat, non-textured braking surface for consistent, powerful braking in all conditions. The rims feature a tubeless profile for use with any road tubeless tyre, and are equally at home with standard tyres and tubes. Wheels are taped ready for tubeless or standard tyres. Valves are available separately – please note that most of these rims require extra-long valves, and our long-base valves with extenders will work on these.

The rear wheels feature our 2:1 spoke lacing pattern with 16 spokes on the drive side, and 8 on the non-drive side. This solves the problem of uneven spoke tensions on rear wheels caused by the offset required for the cassette (wheel dish) and gives our 24-spoke wheels similar strength to conventionally laced 28 or 32 spoke wheels.

The 35, 45 and 55mm rims are normally held in stock, but please contact us to confirm availability.

Valve lengths:  35mm – use our 60mm tubeless valve stems (optional selection below), 45mm use 70mm valves. For 55mm rims you will need a 45mm valve and 40mm extension or 80mm valve (black only).
