The all-new CXR 2 gravel WheelSystem 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 tires and lower pressures, the CXR 2 is as strong as our XCR cross-country mountain bike wheel but at a much lighter weight. - Hookless rim design enhances overall durability and offers a wider inner rim width without adding weight - Optimized carbon layup features high-tensile strength carbon fiber placed at the most crucial structural points to provide stiff, compliant, and lightweight wheels - A 35mm all-round rim profile with a contemporary wider inner width (25mm) offers improved support for today's higher volume road and gravel tires

The SLR 1 Disc WheelSystems are efficient, lightweight, all-around, carbon road wheels that bring premium-level performance to all riders. Featuring hookless rim design and optimized carbon layup to ensure a robust yet lightweight structure, contemporary wider inner width, low friction hubs offering low rolling resistance, and Dynamic Balanced Lacing (DBL) technology to maintain maximum power efficiency, the SLR 1 42 and SLR 1 42 Disc bring outstanding performance at no compromise. - Hookless rim design enhances overall durability and offers a wider inner rim width without adding weight - Optimized carbon layup features high tensile strength carbon fiber placed at the most crucial points to provide stiff, compliant, and lightweight wheels - Low friction hub with precision machined internals eliminates excessive bearing load, reducing bearing friction, lowering rolling resistance, and minimizing power loss - Dynamic Balanced Lacing (DBL) ensures spokes are set for optimal tension when pedaling, resulting in enhanced durability and transmission efficiency - The enlarged DBL hub flange increases spoke bracing angles, boosting overall torsional, transmissional, and lateral stiffness for better power transfer - 42mm-deep all-round rim profile with an updated inner width offers better support for today's higher volume road tires

Power up climbs. Descend with speed and confidence. Stiff, superlight, and built with proprietary technologies, the SLR 0 30 Disc delivers efficiency, control and durability in a stiff, lightweight and value-oriented package. Features - Ultralight 30mm deep full-composite disc brake only rims - Tubeless compatible using supplied rim strips and valves - 17mm internal rim width for optimal tire performance - Dynamic Balance Lacing technology for enhanced drive efficiency and braking control - Sapim straight-pull bladed stainless spokes- 21H Front & 24H Rear - Alloy locking nipples - Giant alloy hub shell, Centerlock Disc rotor mount and pawl based driver system - Includes end caps for the following configurations: - Rear: 142x12mm T/A - 1510g per pair

Fast, efficient and lightweight for long rides through mountain backroads but still tough and durable for big days across relentless gravel as well as fast rips on technical dirt; the all-new, go-anywhere CXR 1 represents the evolution of versatile performance. - Optimized carbon lay-up places high-tensile strength carbon fiber at the most crucial points, ensuring a robust structure at a class-leading weight. - Giant hookless technology further enhances the rim’s durability with a more consistent carbon fiber structure, creating XC-level impact resistance and a rounder tire shape for better grip and handling as well as added sidewall support when cornering. - 25mm inner rim width is apt for larger volume road and gravel tires. - Dynamic Balanced Lacing technology ensures spokes are set for optimal tension when pedaling, resulting in enhanced durability and transmission efficiency, creating a stiffer, more efficient wheel that winds up fast and carries more speed. - 54 tooth DT 350 hub offers near-instant engagement for quick power on technical climbs

The all-new SLR 1 36 Disc WheelSystem provides high-performance versatility, combining maximum power transmission with optimal stiffness, efficiency and weight savings to make it as quick on the climbs as it is confident on the descents.

Zipp's 303 Firecrest Tubeless wheels are designed for the real world—a world of imperfect conditions, varying road surfaces, and elements where the bottom line is simple: efficiency = speed. They're faster, lighter, and more capable over varied terrain—whether the surface is pavement in all its conditions or no pavement at all. Deeply rooted in Zipp's drive to conquer the Spring Classics, the new 303 Firecrest is remade with a purpose-made approach for the demands of modern road bikes. When it comes to going fast on a bicycle, efficiency means reduced wind resistance, rolling resistance, rider fatigue, and weight. The 303 Firecrest Tubeless Disc-brake was designed using real-world direct measurements (vs. primarily wind tunnel or computer simulation). The results were huge. Its rim is slightly more bulbous in design than its predecessor, with a 32mm outside width, a 25mm internal width, and a 40mm rim depth. The profile provides low drag and an improved transition between rim and tire, boosting aero efficiency on the road. The wide rim stance also features less tire deflection for reduced rolling resistance. The combination of the wider tire, increased tire volume, and lower tire pressure helps to reduce rider fatigue by smoothing out the ride over imperfect pavement and road conditions—the tire and wheel system absorbs the shaking, not the rider. The 303 Firecrest Tubeless wheels are for dedicated cyclists who aspire to the latest in technology. They're for those who compete in races, against peers, or simply to conquer personal limits. - New Zipp graphics and cosmetic identity that scream speed - Versatile endurance wheelset for the modern road bike with tubeless and hookless rim profile - Lighter weight than its predecessor, making it nimble and fast - Tubeless Made Easy, optimized tire bed sign allows for simple tool-free installation and removal with no need for an air compressor to seat the tire. - Ultra-wide 25mm rim profile creates a better tire interface to be fast on or off the road - 40mm rim depth makes a light and aero wheel in every situation - Ships with 12mm end caps - Center Lock rotor interface (lockring included)
