Wide 25mm inner rim width ideal for 40-50mm gravel tires or up to 2.3” XC MTB tires. Allows riders to run lower tire pressure, helping enhance traction and control on rough gravel and technical singletrack.
CXR X1 Wheelsystem
Go beyond
Sail smoothly across mixed terrain. Crank up the speed on gravel. Achieve maximum confidence and control on rocky singletrack.The robust and responsive CXR X1 WheelSystem delivers the low weight and durable versatility needed to handle any terrain.
Key Performance Factors
COMPLIANCE & CONTROL
Wide 25mm inner rim width is optimized for 40-50mm gravel tires and can fit XC mountain bike tires up to 2.3”. This wider design provides maximum sidewall support for better cornering performance, and allows riders to run lower tire pressure for reduced rolling resistance and increased compliance and traction. Compliance is further enhanced thanks to shallow weight-saving 25.8mm rim depth.
STRENGTH & DURABILITY
Hookless rim walls with straight, reinforced bead improve carbon structure consistency, helping disperse impact load and boost durability. Precision engineered reinforcements around each spoke hole provide added support precisely where it’s needed without adding unnecessary material.
RESPONSIVE POWER
Optimized carbon layup creates an exceptionally robust and stiff rim structure that shaves weight and enhances transmission efficiency. Dynamic Balanced Lacing technology and cutting-edge Giant instant engagement 60-tooth ratchet freehub provide immediate and efficient power transfer.

Techs & Features
Dynamic Balanced Lacing
Since its introduction in 2015, Dynamic Balanced Lacing (DBL) has been the cornerstone of Giant WheelSystems. DBL ensures that spokes are set for optimal tension when under dynamic load, resulting in enhanced durability and pedaling efficiency. The enlarged DBL hub flange also increases the spoke bracing angles, which boosts overall torsional/transmission and lateral stiffness for better power transfer and more stable sprinting.
Hookless Rim Design
Hookless rim design enhances overall durability, offers a wider inner rim width without adding extra weight and also helps create a more round tire shape providing superior grip and handling as well as added sidewall support when cornering. Additionally, without the rim hook to “push” the tire bead inward, hookless rim design offers a more seamless airflow between the tire and the sidewall of the rim, resulting in less drag and improved aero performance when compared to standard hook-type rims.
