  • Mavic Deemax 21 Boost MTB Wheelset

    Classed by Mavic as one of their most durable wheelsets ever produced, this wheelset is ideal for hardcore gravity riders. With input from the brand's top pro-riders, this model has been developed, tested and proven to conquer the harshest of course conditions. It features a rock-solid asymmetrical aluminium rim design, which allows it to deliver incredible strength when blasting across unpredictable mountain terrains at speed and tackling all the obstacles that come with it. Quick and easy to maintain, it's also equipped with J-bend spokes with two replacement spokes delivered with every wheelset.

    Double-Butted and Bladed Spokes

    This gravity-ready wheelset's alloy rims feature a 28mm internal width with a triangular shape that helps absorb any impacts from rocks to hard landings and big compressions. Mavic's Black Shield treatment gives them a distinctive finish and protects the rims against impacts and scratches. The brand chose a classical J-bend spoke construction using 28 steel spokes (same spoke length throughout), double-butted and bladed for the perfect balance of vertical compliance and strength to handle the abuses of aggressive gravity riding.

    MTB Wheelset with Boost Spacing

    The hubs benefit from Mavic's strongest bearings and the rear hub features the ultra-reliable ID360 double ratchet system for fast engagement to help you accelerate out of the corners. It’s set up for Boost spaced frames and has 6-bolt disc mounts. The wheels include UST tubeless valves, spare spokes and accessories, so you have everything you need to hit the trails.
