The all-new CXR 2 gravel Wheel System showcases Giant's prowess in building strong, lightweight carbon wheels. Through improved carbon layup, innovative hookless technology and a large inner rim width that allows for wider tyres and lower pressures, the CXR 2 is as strong as our XCR cross-country mountain bike wheel but clocks in at a much lighter weight, made specifically for gravel bikes.Highlights:- The all-new Giant CXR 2 Wheel System combines several innovative technologies that make it lightweight and strong.Optimized Carbon Layup:- Placing high-tensile strength carbon fiber at only the most crucial points on the rim and testing through Finite Element Analysis (FEA), Giant's engineers have managed to build a lightweight gravel wheel with superior strength and durability.Optimzied for Wider Tires:- Optimized for 38-40mm gravel tires but also capable handling XC tires up to 2.3Hookless Rim Design:- Hookless technology enhances overall durability, increases impact resistance and offers a wider inner rim width without adding weightFeatures:- Hookless rim design enhances overall durability and offers a wider inner rim width without adding weight- Optimised carbon layup features high-tensile strength carbon fiber placed at the most crucial structural points to provide stiff, compliant and lightweight wheels- A 35mm rim profile with a contemporary wider inner width offers improved support for today's higher volume road and gravel tyresSpecifications:- Rim Material: Carbon- Rim Type: Hookless Clincher- Tubeless: Giant Tubeless System(rim tape and valve kit included)- Rim Height:35mm- Rim Outer Width: 31mm- Rim Inner Width: 25mm- ETRTO: 622-25- Rear Hub: Giant Alloy, Pawl Driver(3 pawl 30T), Centerlock- Hub Compatibility: Shimano HG, SRAM XDR- Bearing: Sealed Cartridge- Rear Axle: 142x12 Thru Axle- Spokes (Rear): SAPIM Sprint- Lacing (Rear): 24H/24H- Nipple Type: Alloy- Weight (Pair): 1518 g- Max weight limit of wheels: 129 kg (bike + rider + kit)Technology: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.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.
