Designed specifically for the challenges of modern gravel riding, the Reserve 40|44 Gravel Carbon Wheelset combines advanced aerodynamic performance with practical versatility to excel in off-road drop-bar adventures.

Developed using Turbulent Aero technology, this wheelset pairs a 40mm front rim with a 44mm rear, making it Reserve’s fastest and most stable gravel wheelset to date. The updated design features a wider internal width to accommodate tires up to 50c, delivering comfort, grip, and control on any terrain. A semi-hooked rim simplifies tubeless setup, while external nipples and standard spokes ensure easy maintenance.

Backed by a lifetime warranty and no-fault crash replacement, the Reserve 40|44 GR offers uncompromising durability — with no tire restrictions and no rider weight limits.

Key Features:

• Mixed Profile Front and Rear
  The mixed profile front and rear setup of the 40|44 GR provides for maximum stability, lowest weight and optimized aerodynamics.
• No Fuss Design
  The 40|44 GR is designed to be your no fuss aero gravel riding and racing wheelset. There are no weight limits, no tire limitations, and can be set up tubeless or with tubes.
• Internal Spoke Reinforcements
  Reserve uses internally reinforced spoke holes to strengthen the area where the rim sees the most force, around the spoke nipple. This provides for improved strength without adding unnecessary weight.
