Mavic’s Deemax Ultimate wheels are developed with and used by some of the fastest racers on the World Cup circuit, and are among the lightest downhill wheelsets. Their alloy rims were developed using Mavic’s patented ISM weight-reduction technology. This technology creates a central line of standard alloy thickness along the rim. This means the weight of the rest of the rim can be reduced to help acceleration and handling, while it stays just as strong—a key element in downhill. The spokes are double-butted and bladed stainless-steel, with 28 in the front and 32 in the rear to cope with the huge hits that are part of racing the clock downhill. And the ITS-4 freewheel system, with 4 pawls and only 7.5 degrees between engaged positions, reduces the acceleration time out of a corner to get back up to maximum speed.
Deemax Ultimate wheels are compatible with multiple axle standards. The front wheel comes delivered with a 20mm axle, but 9mm and 15mm adapters are available separately, and the downhill-specific rear hub has 150mm spacing and includes adapters to convert it to 157mm. The recognizably-yellow Deemax is available in both 26 and 27.5-inch so you can set up your gravity sled so it's fastest for you.
