This wheel is the future of gravity riding and racing. It's ride-optimized, incredibly strong, and debuts the most effective and lightest anti-flat system on the market (ENVE's patent-pending Protective Rim Strip). These wheels will give downhill-oriented riders a new freedom to set their tire pressure for cornering and rock garden stability without sacrificing their confidence to smash track speeds. Who It's For Gravity junkies, Enduro racers, and hard-charging trail riders will find enlightenment riding the M7 Series. A completely new shape and design that massively reduces the risk of pinch flatting and/or damaging the carbon, the M7 Series provides the confidence to ride without limitations. Why We Made It Enduro runs on two things – Confidence and Control. Nothing ruins a good shred fest like a flat tire or broken rim, and nothing spooks you on a dusty trail like an unexpected drift. With this in mind, we have been hard at work over the past 2 years to develop a carbon wheel system that will allow ourselves, athletes, and most importantly – you – to go "full-send" without compromising the ride experience by running high tire pressures, DH tires, and heavy pinch flat reduction inserts. Building upon the platform of the M7 Series' predecessor the M70, we re-profiled the rim to mate up with modern tires and to absorb trail vibrations and chatter. However, just fitting tires is not enough. We know that riders also want the freedom to run lower pressure and that doing so can introduce flat tires and damaged rims. The ENVE solution is a new rim shape paired with ENVE's patent-pending, energy-absorbing Protective Rim Strip. With this technology, riders can skip the inserts and run the tires and pressures they want. Amazingly, we've managed to keep the weight neutral and improve impact resistance too.

New Sheriff hubs are the ultimate in track racing hubs. They minimize weight with larger cutouts in the flanges, lightened axles, shorter bolts, and slimmer end caps than previous versions. The result is a hubset that weighs a mere 432g, 198g for the front, and 234g for the rear. This makes it one of the lightest track hubsets in the world, a figure even more impressive when you consider that All-City didn't eliminate the usefulness of a fixed / fixed or fixed / free option as most racing hubs do. They feature the finest Japanese manufactured 6902 bearings which roll incredibly fast and smooth while retaining excellent seals for all weather, all-day everyday durability. Front hub specs: - Weight: 198g - Torque Spec: 33nm (25ft lbs.) - Non-Drive Side Center to Flange: 34mm - Drive Side Center to Flange: 34mm - Non-Drive Side Flange Diameter: 62mm - Drive Side Flange Diameter: 62mm Rear hub specs: - Weight: 234g - Torque Spec: 33nm (25ft.lbs.) - Non-Drive Side Center to Flange: 29mm - Drive Side Center to Flange: 29mm - Non-Drive Side Flange Diameter: 62mm - Drive Side Flange Diameter: 62mm

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)
