Purpose - With the resurgence of XC and the explosion of gravel, we had the vision to develop a rim that would offer maximum comfort and deliver the confidence for the rider who chooses the lightweight hardtail over a dually. The layup has been completely redesigned and offers high strength with the lowest radial stiffness possible. Pair this with our industry-leading out of mold tolerances, and you can bring on the long days in style! Tires - The tires we recommend are 38c and up for gravel. For XC 2.1 - 2.25 tires would be ideal. 29/700 Only

Zipp's 302 Tubeless rim-brake wheels deliver dependable speed for aspiring and experienced cyclists alike. These wheels provide great value and performance and are now tubeless, allowing you to run lower tire pressure for greater cornering grip and reduced rolling resistance without the risk of pinch flats. Its 45mm deep, Indianapolis-made carbon rim is optimized for low aerodynamic drag and precise handling in all riding conditions. The 302's smooth carbon rim is laced to Zipp's 76 hub using Belgian CX-Sprint spokes and brass spoke nipples to build a wheel that is fast and reliable—tough enough to thrive in the big Gran Fondo or the road less traveled, yet light enough to tackle the steepest grades. The 302 is equally suited to training rides or duking it out at your local race series. - Tubeless design provides secure performance when riding at lower tire pressures - New Zipp graphics and cosmetic identity that scream speed - Dependable 76/176 hubs with Sapim CX Sprint J-bend spokes - Ships with QR end caps and quick release skewers

The definition of "road cycling" now includes gravel and dirt as well as pavement. At the same time, bikes are evolving to meet the fit requirements of smaller riders. Meeting these two distinct needs was the driving force behind the Zipp 303 Firecrest 650B Tubeless Disc-brake wheelset. The smaller rim size provides room within frames and forks for larger tires that deliver increased comfort, compliance, and cornering performance. With more tire between the rim and the ground, the overall wheel diameter, including the tire, is similar to a standard 700c wheel and road tire combination. Back on the pavement, the 650B is a better-fitting wheel for smaller athletes riding compatible frames. For too long, many smaller cyclists have trained and raced on standard 700c wheels, losing out on the advantages of a proper fitting wheel such as improved handling and the elimination of front wheel-toe overlap. At the center of the 303 650B Firecrest Tubeless is a versatile and durable hubset, the German-engineered ZR1 DB. - Zipp graphics and cosmetic identity that scream speed - Versatile 45mm rim profile for increased speed and better cornering, control, and comfort - Tubeless design provides secure performance when ridden at lower tire pressures - ZR1 DB hubset is engineered in Germany with better seal design for improved durability and quicker response with 66 points of engagement - Built with Sapim CX Sprint J-bend spokes - Center Lock rotor interface (lockring included) - Ships with 12mm end caps

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)
