Shimano GRX – United in Gravel

Gravel is the great equalizer. No matter who you are, where you come from or where you want to go. Gravel celebrates individuality. It welds together in a shared passion. It lays the foundation for friendships and creates memories for the ages. Whether you ride one kilometer or a hundred. Whether with professional equipment or without. With a 10-speed, 11-speed or 12-speed gear system. Whether on paved roads, forest roads, back roads – or no roads at all. It does not matter why you are out there, all that matters is that you are.

Shimano GRX WH-RX880-TL wheelset

Faster, Further & more Fun. Equipped with the same flat rim height (32 mm) as its predecessor, but 64 grams lighter per pair, the GRX WH-RX880 wheels offer even faster acceleration and more agile climbing. While the low rim profile furthermore ensures better control in crosswinds, the inner width of 25 mm makes the use of wide tires up to 50 mm possible. 24 robust J-Bend spokes ensure even during intense adventures for an inimitable reliable connection of the Tubeless suitable full carbon rims with the lightweight aluminum hubs.

The rear hub of the WH-RX880 wheelset features the Direct Engagement technology borrowed from Dura Ace series, which provides a fast and efficient power connection for rapid acceleration on any terrain. The user-friendly design of the hub is also characterized by the ability to easily switch between the road bike specific HyperGlide L2 and the Micro Spline freewheel, which is already proven in the MTB segment.

Direct Engagement | In extensive tests, various prototypes were compared with a respective focus on drive, lateral and longitudinal stiffness. The result: the drive stiffness has the strongest influence on the drive force. This finding was the basis for the development of the Direct Engagement system, which increases the drive stiffness accordingly compared to the conventional pawl structure. This is achieved on the one hand by a larger contact surface and on the other hand by the toothing, which, thanks to its spiral shape, engages more tightly when the drive forces are applied.
