Shimano RX570 Rear WheelDiscover the ultimate in gravel performance and reliability with the SHIMANO RX570 Gravel Disc Tubeless road rear wheel. Engineered specifically for the demands of mixed-terrain riding, this wheel is your steadfast companion for tackling everything from smooth tarmac to rough fire roads and challenging singletrack. As a core component of Shimano´s renowned GRX series, the RX570 is built to provide confidence-inspiring control and durability, allowing you to explore further and push your limits on every adventure.The primary advantage of the RX570 lies in its gravel-tuned design. This Rear wheel utilizes the versatile 27.5´´- 650B size, enabling the use of wider, higher-volume tires. This translates directly to superior comfort over rough surfaces, absorbing vibrations and reducing rider fatigue on long journeys. The increased tire contact patch also delivers exceptional traction and cornering grip, giving you the confidence to maintain speed and control through loose gravel and technical descents. The robust Aluminum construction ensures the wheel can withstand the rigors of off-road use while remaining responsive and efficient.Designed for modern gravel bikes, this wheel is fully optimized for a tubeless setup. The 21.6 mm internal rim width provides an ideal platform for wider gravel tires, ensuring a perfect tire profile for maximum performance. Running tubeless allows you to use lower tire pressures for enhanced grip and a smoother ride, with the significant benefit of drastically reducing the risk of punctures. The integration of a Center Lock Disc Brake mount provides powerful, consistent, and easy-to-modulate braking in all weather conditions, a critical feature for safe and controlled descending. The wheel´s Low profile < 30 mm rim design is less susceptible to crosswinds and contributes to its nimble handling characteristics, making it perfect for the unpredictable nature of Gravel cycling. Built with Shimano´s legendary precision, the E-Thru axle system ensures a stiff and secure connection to the frame, improving power transfer and overall handling accuracy.
