Sram HG Black – Sram XD Black

With the GPX we introduce an ultra-lightweight graphene MTB rally and marathon wheelset with 30mm internal rim width. The new SPR technology is a specific reinforcement in the spoke hole area, which allows for a huge weight reduction without sacrificing stiffness or durability. With this new rim we improve traction and cornering grip as well as torsion, shock and reactivity. Without much delay we conclude the testing phase by achieving some top 10 results in the XCM World Cup. This winning set comes with the Nitro ceramic hubs.
