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. At the center of the 303 Firecrest Tubeless is a versatile and durable new hubset, the German-engineered ZR1 DB. This hubset features 66 points of engagement for quicker response. 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)

CZR i23 gravel wheels are designed to minimize weight while blending stiffness and compliance to maximize power transfer and increase comfort. CZR i23 rims feature a 24mm section depth to maximize energy transfer, reduce weight, improve vertical compliance, and reduce rider fatigue while a hooked bead also improves tire retention with high-pressure adventure road and gravel tires. CZR I23 CARBON RIMS Reinforced spoke beds improve overall wheel strength and durability while also minimizing weight in areas where less strength, and therefore material, is needed. CZR i23 rims feature 3mm of asymmetrical spoke offset and a 24mm section depth to improve radial stiffness and maximize energy transfer without being affected by crosswinds like other wheels with deeper profiles. SOLID STRIP & TCS TAPE Durable nylon strip that lies between the rim and tubeless tape to prevent tubeless tape from pushing into the spoke holes and ensures a smooth interface between the tire and rim. The smooth surface makes it easier to mount a tire by preventing air from escaping around the bead at each indent during inflation. Solid Strip also protects the airtight system from puncture in the case of a broken spoke. 2-CROSS OR 3-CROSS LACING CZR i23 gravel wheels with 24 spokes feature a 2-cross lacing pattern to increase radial stiffness and decrease weight. CZR i23 wheels with 28 spokes feature a 3-cross pattern to increase durability while still providing ample radial stiffness due to the additional spokes. FREQUENCY HUBS The world's best carbon rims deserved to be paired with high-quality hubs that further improve the performance of a lightweight, dependable carbon wheelset. Frequency hubs feature a low-drag, 6-pawl design that alternates contact between two sets of 3-pawl groupings to provide a responsive 5 degrees of freehub engagement. Frequency hubs laced to CZR i23 wheels feature lightweight pawl springs that minimize drag and therefore improve efficiency for drop-bar usage. AERODYNAMIC WING SPOKES Pillar racing spokes that are cold-forged into an aerodynamic wing shape that reduces drag at the trailing end of each spoke. As a result, wing spokes improve overall efficiency while still retaining the gram-conscious weights of traditional bladed spokes. SAPIM ALLOY NIPPLES All CZR i23 wheels feature time-tested Sapim alloy nipples to further reduce overall wheel weight while still exceeding the durability requirements of gravel. Countless Configurations CZR i23 wheels are available in a 24-spoke option for riders looking to minimize weight and increase compliance, while the 28-spoke versions are best for heavier or more aggressive riders who prioritize stiffness and durability. All CZR i23 wheels are available with Centerlock or 6-bolt rotor mounts. CZR i23 front wheels use a 12x100mm Frequency hub, but 15mm end caps are also available separately. Why Choose CZR i23? Fast and light CZR i23 gravel wheels were designed to minimize weight and maximize compliance on rough gravel roads. With front-wheel weights starting at 620g and rears at 775g, they also deliver the greatest strength-to-weight ratio of any gravel wheelset on the market. We even stand behind them with our Ride With Confidence Guarantee for those few-and-far-between crash replacement cases.
