PROGRESS Wheelset SET GPX NITRO2 29 BOOST 15X110/12X148 MICROSPLINE PGRUGPXN229BJMSNJ

With the GPX, we introduced an ultralight graphene wheelset for MTB rally and marathon, featuring a 30mm internal rim width. The new SPR technology is a targeted reinforcement in the spoke hole area, allowing for significant weight reduction without sacrificing stiffness or durability. This new rim improves traction and cornering grip, as well as torsional rigidity, impact resistance, and responsiveness. We quickly completed the testing phase, achieving some top 10 results in the XCM World Cup. This winning set comes with NITRO 2 ceramic hubs with 4 pawls and 48 teeth.
Graphene is the material of the future and the lightest discovered to date.
With the GPX we introduced ultra-lightweight MTB wheels for Rally and Marathon with an internal rim width of 30mm.
Manufactured with Graphene and the best carbon fiber (Toray), which is 11 times stiffer than the hardest aluminum known, if we add an extra width to the rim, we achieve the best relationship between stiffness and lightness.
All of this, combined with our Nitro 2 hubs featuring high-precision, low-friction ceramic bearings and Sapim CX-Ray Straight Pull spokes, gives these wheels superior lateral stiffness, transforming all your effort into greater speed.
