Wider Carbon Fibre Rim for Better Aerodynamics The 303 Firecrest Tubeless Disc brake wheels were designed using real-world direct measurements (vs. primarily wind tunnel or computer simulation). This included Zipp’s RollingRoad™ Testing Protocol. The results were huge. Its rim is slightly more bulbous in design than its predecessor, with a 30mm outside width, a 25mm internal width and a 40mm rim depth. The profile provides low drag and an improved transition between rim and tyre, boosting aero efficiency on the road. Faster Performance These wheels are faster, lighter and more capable over varied terrain, whether the surface is tarmac in all its conditions or no tarmac at all. Deeply rooted in Zipp’s drive to conquer the Spring Classics, the revised 303 Firecrest is redesigned with a purpose-made approach for the demands of modern road bikes. This is the first Zipp wheelset to feature TSE™ Technology (Total System Efficiency). The 303 Firecrest’s precise rim layup results in greater all-around efficiency for greater speed through reduced wind resistance, rolling resistance, a lower weight, increased durability and vibration losses. More Comfortable Ride on Mixed Terrain The wide rim stance also features less tyre deflection for reduced rolling resistance. The combination of the wider tyre, increased tyre volume and lower tyre pressure reduces rider fatigue. This is because the ride is smoother over imperfect surface conditions as the tyre and wheel system absorbs the shaking, not the rider. At the centre of the 303 Firecrest Tubeless Disc brake is a versatile and durable hubset, the German-engineered ZR1 DB. This hubset features 66 points of engagement for quicker pedalling response. The 303 Firecrest Tubeless Disc-brake wheelset is for those after greater efficiency for greater speed. The payoff is a smoother, faster ride. Additional Features: Updated Zipp graphics and cosmetic identity that scream speed Versatile endurance wheelset for the modern road bike with tubeless and hookless rim profile Lower in weight - a 300g weight reduction than its predecessor, making it nimble and fast Tubeless Made Easy, optimised tyre bed sign allows for simple tool-free installation and removal with no need for an air compressor to seat the tyre Ultra-wide 25mm rim profile creates a better tyre interface to be fast on or off the road 40mm rim depth makes a light and aero wheel in every situation ZR1 DB hub is engineered in Germany with better seal design for improved durability and quicker response with 66 points of engagement Ships with 12mm front and rear end caps Centre locking rotor interface Lockring is included with the wheels Lifetime Warranty

Zipp’s 808 Firecrest® Carbon Clincher is pure engineering science. It has to be. To achieve speed with an 82mm rim depth is one thing, but to be fast but also high crosswind stability, well, that requires serious attention to detail. Yet that’s just what the 808 Firecrest Carbon Clincher accomplishes – speed with stability, what we call AeroBalance™ – which has made it a longtime favorite of triathletes, time trial specialists, as well as any cyclist in search of free speed. At Zipp, that search for aero efficiency is unrelenting. To that end, the latest iteration of the 808 Firecrest Carbon Clincher provides more speed, better control, and greater stopping power than its predecessor: More Speed: Revised rim profile for reduced aerodynamic drag developed by our advanced development team in Indianapolis, Indiana, USA. Greater AeroBalance™: ABLC™ Sawtooth™ Technology, a complex dimpling pattern first developed for our top-level NSW wheel lineup. This technology helps reduce high yaw drag while improving crosswind stability. This helps to achieve the optimization of low aerodynamic drag and crosswind stability, which we call AeroBalance. Better braking: Zipp’s ShowStopper™ textured braking surface delivers unrivalled rim braking performance in wet or dry conditions. Lighter Weight: The 808 Firecrest Carbon Clincher is 55 grams lighter than its previous iteration.
