The gravel purist’s uncompromised manifesto.
GRX Series wields a 28mm hookless fortress – where width meets wrath. Designed to devour 50mm knobbies and spit out mud, its non-asymmetric profile channels raw stability for those who dance with chaos.
Two heights define your rebellion: 40mm for technical singletrack sorcery, 50mm for sustained gravel grind alchemy. The V2-V3 layup twins offer a binary creed – V2 for all-day brutality, V3 for gram-shaving velocity – both baptized in hookless’ holy trinity of strength, simplicity, and tubeless nirvana.
When the road ends, the GRX begins.

Rim Height
In cycling, rim height significantly impacts the aerodynamics, agility and weight of the wheel. The general principle is the higher the profile of the rim, the greater the aerodynamic advantage; the lower the profile of the rim, the greater the response and better the handling when cornering and changing speed.
