The GR45 Pro brings aero carbon speed to gravel and all-road riding, with a wide 25mm internal rim, tough steel spokes and a tubeless-ready rim bed that needs no tape.

Highlights

  • 45mm HI-MOD carbon rims
  • 32mm external / 25mm internal width for 35c and wider tyres
  • Pillar Wing 20 steel spokes, 24H front and rear
  • Tubeless ready: no spoke holes, no rim tape needed
  • 1490g per pair (±3%, without valves)
  • UCI approved

Width for gravel tyres

A 25mm internal width supports 35c and wider tyres, reducing tyre roll in corners and letting you run lower pressures for grip and comfort on rough surfaces.

Steel spokes for rough roads

Magene chose Pillar Wing 20 steel spokes over carbon here for vibration absorption, impact resistance and durability. The front uses 1:1 lacing with crossed spokes on both sides; the rear uses 2:1 lacing for drive-side stiffness.

Swappable ratchet

The 36T flat ratchet engages quickly and cleanly, and the system is designed to take ratchets with different tooth counts.

Compatibility & fit
