Sail smoothly across mixed terrain. Crank up the speed on gravel. Achieve maximum confidence and control on rocky single track. The robust and responsive CXR X1 Wheel System delivers the low weight and durable versatility needed to handle any terrain.Highlights:Broad Inner Width:- 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 single track.Reinforced Hook less Bead:- Hook less rim walls with straight, reinforced bead improves overall durability and increases impact absorption on broken asphalt and rocky terrain.Ideal Depth:- Shallow 25.8mm rim depth keeps the CXR X1 light and compliant when rolling over mixed terrain.Features:- Wide 25mm inner rim width and hook less bead provide increased support for higher volume road, gravel and XC mountain bike tires- Shallow 25.8mm rim depth adds compliance and saves weight- Rim bead reinforcement disperses impact load and enhances rim strength without increasing weight- Precision engineered reinforcements around each spoke hole provide support exactly where it's needed without adding unnecessary material- Dynamic Balanced Lacing technology creates perfect amount of spoke tension for optimal transmission stiffness and braking performance- Giant instant engagement freehub with 42CrMO 60-tooth ratchet driver with Diamond-Like-Coating utilizes durable flattened coil spring to deliver immediate and efficient power transfer- Integrated axle front hub provides a more robust structure, eliminating play and enhancing lateral stiffnessSpecifications:- Rim Material: Carbon- Rim Type: Hook less Clincher- Tubeless: Giant Tubeless System (rim tape and valve kit included)- Rim Height: 25.8mm- Rim Outer Width: 31mm- Rim Inner Width: 25mm- ETRTO: 622-25- Rear Hub: CXR Alloy 60t Ratchet, Center lock- Freehub: Shimano HG (Optional SRAM XDR freehub available)- Bearing: Sealed Cartridge- Rear Axle: 142x12 Thru Axle- Spokes (Rear): SAPIM LASER- Lacing (Rear): 24H DBL- Nipple Type: SAPIM Double Square- Weight (Pair): 1430gTechnology:Dynamic Balanced Lacing:- Since its introduction in 2015, Dynamic Balanced Lacing (DBL) has been the cornerstone of Giant Wheel Systems. 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.Hook less Rim Design:- Hook less 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, hook less 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.Tubeless System:- Fewer flat tires. Greater traction. Less rolling resistance and a smoother, faster ride. Giant's Tubeless System makes it easier than ever to experience all these benefits.
