Reserve's newest aero gravel race wheels are built to deliver more speed and more grip. A 30mm inner rim width creates a round, wide-stance tire and a larger contact patch. The super-wide external profile delivers noticeable aero advantages, allowing air to glide uninterrupted between the tire and rim sidewalls.

Featuring a new innovative wide hollow-bead design, 48|53 GR wheels shave weight from the outermost section of the rim while also better preventing pinch flats.

These are the fastest off-road wheels Reserve has ever made. 

FEATURES:

• 30mm Internal Width: Optimized for modern 40–57mm gravel tires, the 30mm internal width creates a wider tire profile and larger contact patch for increased grip, stability, and confidence across varied terrain.
• Aero-Optimized Rim Profile: A super-wide 44mm external profile helps airflow transition smoothly between the tire and rim, reducing aerodynamic drag and improving efficiency at speed.
• Hollow Hook Construction: New Hollow Hook construction removes weight from the outer edge of the rim while maintaining exceptional durability and pinch-flat protection for race-ready performance.
