Description
Reserve 48/53 GR Carbon Gravel Wheelset | DT 180 Xdr/HG11
The Reserve 48/53 GR DT 180 is the fastest off-road wheelset Reserve has ever made. Built for gravel racers chasing every advantage, it combines Turbulent Aero technology with a wide hollow-hook rim to deliver more grip, more speed and more protection against flats. The mixed-depth design improves stability in crosswinds while boosting aerodynamic efficiency for all-day racing.
The 44 mm external width smooths airflow for maximum aero performance, and the 30 mm internal width is tuned for modern gravel tyres. The result is greater grip, stability and confidence on loose terrain. The lightweight hollow-hook construction keeps weight low without sacrificing strength or pinch-flat protection, backed by Reserve’s lifetime warranty.

Aero Optimization
The super-wide 44 mm external rim profile allows air to transition smoothly across the tyre and rim, reducing drag and increasing speed. This buffer of smooth airflow is key to improving aerodynamic performance on fast gravel courses.
Hollow Hook Design
The hollow-hook design removes excess material inside the rim, keeping weight low while maintaining strength and pinch-flat protection. This allows for a super-wide rim profile without a weight penalty.
30 mm Internal Width
The 30 mm internal width supports modern gravel tyres, creating a wider contact patch for more grip. It also prevents tyres from lightbulbing, keeping sidewalls stable for better control and confidence.
Performance
The shallower 48 mm front rim improves stability in aggressive crosswinds, while the deeper 53 mm rear rim boosts aerodynamic efficiency without affecting steering. Every dimension is tuned for speed, stability and race-day confidence.
