It combines the brand's experience in the areas of MTB and road - perfect for this discipline. All elements are matched to each other to create a harmonious whole. A confident choice regardless of how you ride. Designed for gravel. These wheels were developed from the ground up for gravel riding. Their heart is stiff, shock-resistant and perfectly sealed hubs. The carbon rims are wide to work best with wide tires and utilize their capabilities, and also translate into maximum performance. They are connected by butted straightpull spokes - light and durable. This set is perfect for both racing and long, demanding expeditions. Specification: The Shimano WH-RX870-TL front wheel was created for gravel, cyclocross, and trekking use and is the perfect complement to the Shimano GRX drive group. Thanks to the carbon rim with a depth of 32 mm and an internal width of 25 mm, this wheel provides an optimal combination of lateral stiffness, low weight, and aerodynamics, even at low tire pressure. The rim is adapted for riding with both a tube and tubeless (Tubeless Ready) and allows the installation of tires with a width of 32 up to 50 mm. Thanks to the dropout design, the rim provides better tire support at lower pressure, which is especially important when riding on loose or uneven surfaces. The hub, supported by conical roller bearings (Cup & Cone), is characterized by high durability and smooth operation. High-quality machining (CBN) and contact seals guarantee reliability in off-road conditions. The 12x100 mm thru-axle mounting (E-Thru) ensures torsional stiffness and better steering precision in corners. The entire assembly is laced with 24 straight, double-butted aero spokes (2.0–1.6–2.0 mm), made of stainless steel, with aluminum nipples.
