Reserve 48/53GR DT180 2026: high-end carbon wheels for gravel riding

A pair of tubeless-ready carbon wheels with DT180 hubs

Carbon gravel wheels Reserve 48|53 GR DT 180 These wheels are designed for gravel racers looking for a speed-oriented wheelset for the fastest courses. They combine a 48mm front rim, a 53mm rear rim, Turbulent Aero technology, and a wide Hollow Hook construction designed to combine aerodynamics, control, and pinch protection.

The differentiated profile addresses the specific constraints of each wheel. The 48 mm front rim limits unpredictable reactions in strong crosswinds, while the 53 mm rear profile improves aerodynamics without directly affecting steering precision. Both rims have an external width of 44 mm and an internal width of 30 mm.

This DT 180 version has a claimed weight of 1433g per pair, which is 95g less than the DT 350 version according to the provided data. It comes with both XDR and HG-EV freehub bodies, as well as a Reserve rim tape installed, two Fillmore tubeless valves, and white rim stickers.

Differentiated design 48|53 GR

48 mm front rim

The front wheel uses a 48mm deep rim. This shallower profile is designed to limit unpredictable reactions when crosswinds become strong.

53 mm rear rim

The rear wheel receives a 53 mm rim. This taller profile enhances the aerodynamic work at the rear without directly altering the steering precision.

Constant speed on fast courses

The 48|53 GR combination is designed to maintain consistent performance throughout fast gravel events, with predictable and smooth handling.

Turbulent Aero Technology

Aerodynamic optimization

Turbulent Aero technology is used to develop rim profiles under varying airflow conditions.

44 mm external profile

The 44 mm external width allows air to flow more smoothly around the tire and rim. This continuity aims to reduce aerodynamic drag.

Transition between tire and rim

The profile is designed to work with modern gravel tires and achieve a smoother transition between their casing and the outer surface of the rim.

Hollow Hook Construction

Semi-hook rim

The Reserve 48|53 GR uses a semi-hook Hollow Hook construction designed to produce a very wide rim without adding unnecessary material.

Hollow internal structure

Removing excess material inside the hook area allows for a wide construction while controlling the rim weight.

4.5 mm hook

The hook width reaches 4.5 mm. This enlarged surface area helps to distribute the stresses exerted on the tire during impacts.

Pinch protection

The Hollow Hook construction is designed to provide effective pinch protection on uneven gravel terrain.

Internal width of 30 mm

Suitable for modern gravel tires

The 30mm internal width is optimized for current gravel tires. Reserve recommends tire sizes between 40 and 57mm.

Contact surface

The rim width allows the tire to take on a wider shape, creating a larger contact area with the ground.

Reduction of the bulb effect

This design limits the blister effect, in which the sidewalls tighten at the rim before the tire reaches its maximum width.

Adhesion and stability

The resulting profile aims to improve grip, stability and confidence on both fast tracks and more irregular sections.
