Reserve 40/44 Aero Gravel Wheelset for Drop Bar Riding and Racing

All-Day Capability with Aerodynamic Sensibility
Designed to deliver comfort and speed across all terrains, the Reserve 40|44 blends a wider, shallower 40 mm front rim with a narrower, taller 44 mm rear rim for an ideal balance of stability and aerodynamic efficiency

Key Features & Benefits

• Mixed Front/Rear Profile
  The 40 mm front rim cuts through the air with precision and agility, while the 44 mm rear rim enhances stiffness and drive responsiveness—especially useful on varied terrain.

• Wide Rim Design for Exceptional Comfort & Tire Versatility
  With internal widths of 25.5 mm (front) and 25 mm (rear), and external widths of 33 mm / 31 mm, these rims pair best with tires sized 28–40 mm. The generous profile yields a smooth ride feel and excellent crosswind stability.

• Superior Construction and Durability
  Built with internally reinforced spoke holes to strengthen high-stress areas without adding extra weight.

• Tool-Free No-Fuss Design
  Compatible with both tubeless setups and traditional tubes, with no restrictions on tire width or rider weight.

• Reliable Hub Options and Smooth Engagement
  Available with DT Swiss hubs (350, 240, or 180)—each offering sealed cartridge bearings, Centerlock rotor mounts, and Shimano HG or SRAM XDR freehub options.
