Santa Cruz Reserve HD

The 6069 aluminum alloy is specifically chosen for its superior strength-to-weight ratio compared to the more common 6061 alloy. This allows the Reserve HD rims to be thinner and lighter while maintaining the impact resistance needed for aggressive, high-speed trail riding.

A 30mm internal width is the current sweet spot for modern trail and enduro tires, typically ranging from 2.3 to 2.6 inches. This width provides a stable platform that prevents the tire from squirming or folding over during hard cornering, giving you more predictable traction.

Yes, the 90T DEG (Degree) system provides extremely fast engagement, meaning there is almost zero lag between when you start pedaling and when the rear wheel moves. This is particularly helpful for technical climbing where you need to ratchet your pedals over obstacles without losing momentum.

These wheels come with an XD driver body, which is compatible with SRAM 11-speed and 12-speed Eagle cassettes. If you are running a Shimano drivetrain, you will need to swap the driver body to a Micro Spline version.

Yes, the Reserve HD is available in both full 29-inch and MX (Mullet) configurations. If you are running an MX setup, ensure you select the correct rear wheel size to match your frame's geometry requirements.

These wheels are built with a 6-bolt disc brake interface. If your current bike uses Centerlock rotors, you will need to switch to 6-bolt rotors or use a Centerlock-to-6-bolt adapter.
