Reserve 31|DH

Let’s face it, modern downhill tracks are not for the faint of heart. From the moment you drop in, it’s a hari cari mix of boulders, roots, bumps and jumps awaiting you, and literally the only thing keeping you upright and connecting you to the ground is your wheels. We know it’s serious business, and the abuse of a day riding DH is no joke. But we’ve got your back with the Reserve DH wheels. Tested to victory with the Santa Cruz Syndicate on the World Cup DH circuit, it is the carbon wheelset that delivers confidence when you need it most.

Ebike Compatibility

We have paired the Reserve 31|DH rear wheel with a Reserve 30 and 30|HD Front for use on our ebikes. The added strength of the rear wheel compliments the additional weight of an ebike and the proven design of the Reserve 30 will keep you headed in the right direction.
