ZTTO R1S / R2 Road Bike Tubeless Ready Disc Brake Wheelset

High-Performance Aluminum Alloy Construction
Engineered from premium aluminum alloy, this 700C wheelset delivers an outstanding balance of lightweight performance and durability. With a 27mm external width and 22mm internal width, the 30mm deep rim offers an excellent combination of aerodynamics, stiffness, and control — ideal for various road conditions and long-distance rides.

Tubeless Ready Design
Designed for modern performance, the rim is tubeless-ready while also compatible with traditional clincher tires. Run lower tire pressures for enhanced comfort, grip, and speed without the risk of pinch flats. This setup ensures smooth rolling efficiency and improved cornering stability on all terrains.

Advanced Hub System
The R1S hub features a 6-pawl system with 72 engagement points per revolution for immediate power transfer. The R2 hub adopts a 36T ratchet mechanism, providing reliable engagement and long-term durability. Both hubs use sealed cartridge bearings (front: 15267/6802, rear: 6902) for smooth and consistent rotation in all weather conditions.

Multiple Axle Compatibility
Each wheelset includes 4 interchangeable side caps for both front and rear hubs, allowing easy conversion:
Front: 12x100mm thru axle / 9x100mm QR
Rear: 12x142mm thru axle / 10x135mm QR
This flexibility ensures compatibility with most modern and classic road bike frames.

Center Lock Disc Brake Ready
Fully center lock disc brake compatible, the wheelset provides powerful and consistent braking performance even in wet or steep conditions. The center lock design also enhances wheel stiffness and makes rotor installation fast and precise.

Spoke Technology
Equipped with 24 straight-pull bladed spokes (1.4x2.3mm steel) front and rear, this configuration ensures balanced tension and aerodynamic efficiency while maintaining excellent strength-to-weight ratio.

Weight and Performance
Total weight is approximately 1854g (HGR body), offering a lightweight yet robust setup. The XDR freehub option provides a slightly lighter configuration for riders seeking maximum efficiency.

Optimized Aerodynamics & Stability
The 30mm rim depth provides proven aerodynamic benefits while maintaining responsive handling. Whether climbing, sprinting, or descending, this wheelset remains agile, stable, and performance-driven under all conditions.
