Zipp makes the impossible possible with their 303 Firecrest Carbon Disc Brake wheels—they're equally at home on the flats as they are in the mountains. The 45mm-deep rims slice through the wind more efficiently than even many deep-section wheels thanks to their 28.5mm-wide dimpled rims. And, by creating a seamless junction between rim and tire, the increased width further reduces drag. The 303s climb with the best and re-accelerate out of corners like rockets since they barely register on the scale, which makes them a must-have on undulating terrain. The extra wide rim also allows running wider tires at lower pressures with less fear of pinch flatting, which boosts ride quality and comfort and reduces rolling resistance. Plus, Zipp's 77D/177D disc hubs gives you incredible stopping power in wet and dry conditions alike, and they're thru-axle compatible (sold separately) for jaw-dropping steering precision and power transfer. You also get Sapim's oustanding CX-Ray spokes.

What It Is The definitive mountain wheel. The M6 Series defines the modern and varied interpretation of the mountain bike. Loaded with traction and acceleration on the climb, it's also backed with precision and control while absorbing vibrations and impacts on the descent. The M6 Series is designed in two diameters and three widths to ensure your sophisticated preference for tire size and pressure is met with an uncompromising tire-to-rim interface. Who It's For The mountain biker who wonders what is possible, the skeptic afraid of "plastic" wheels, the weight weenie, the Clydesdale, the high-mileage guy, the weekend warrior. It would be easier to describe who it is not for… Why We Made It ENVE showed the world that a mountain bike wheel could be carbon — we're still immensely proud of that achievement. A mountain bike wheel, however, can be so much more. The M6 Series is not about technical challenges, and we refuse to chase specifications in order to be the widest, tallest, or stiffest. For the M6 Series of wheels, the question was not about carbon, rather, "What is the potential of a mountain bike wheel?" Each M6 Series wheel model is designed for the broad range of tire widths, hub configurations, and sizes so that you, the modern trail rider, can choose between them.

Front SealLock end caps for Neo OS and Neo Ultimate OS hubs. SealLock end caps feature a low-friction U-cup seal that snaps into place and stays secure even when your wheel is removed from your bike. Not compatible with non-OS hubs or Centerlock hubs.

SRAM's X0 conversion caps are the ticket for converting your X0 hubs to a different axle type.

What It Is The SES 3.4 AR is the embodiment of the modern disc brake-only road wheelset. Aerodynamically optimized for high-volume tires (28 - 32mm), lightweight for long days in the mountains, high volume for all roads, and arguably the most versatile wheelset ENVE has ever made. Science & Insight In 2016 we launched the SES 4.5 AR, a wheelset ahead of its time. Since then, road riders, frame manufacturers, and tire makers have all caught the high-volume vision which has propelled the one-of-its-kind 4.5 AR to be our most popular wheel in North America where the high-volume all-road movement has gained the most traction. As more bikes are created that can accommodate tire clearances up to 32mm, we saw the need to create a more versatile, climber-friendly SES AR wheelset, and the SES 3.4 AR was born. Points of Differentiation - Real-world aerodynamics, optimized around 28mm to 32mm tubeless tires - Wide, Hookless Bead Anti-Pinch Flat Technology - Disc brake-specific materials and construction - Low weight leader in category - Tubeless-only design

What It Is A purpose-built XC wheelset without limitations. Light enough to race, strong enough to ride daily. Reduced fatigue and a more compliant ride through shape, laminate, and spoke-hole optimization. Who It's For Modern XC racers and riders who demand equal uphill and downhill performance, light weight, durability, and vertical compliance for long hours in the saddle. Why We Made It Carbon fiber is responsible for unlocking the potential of bigger and wider tires on mountain bikes. Today, riders can improve comfort, efficiency, and control by adapting their mountain bikes perfectly for the terrain and trails. Undoubtedly, this means they can go further and faster with more confidence. Complement increased tire volumes and rim widths with a modern XC tread, and you've got an effective system, maximized for the variable-pitch trail. The result is a purpose-built full-carbon fiber XC wheelset that is lighter, wider, and more vertically compliant without sacrificing strength or reliability. Additionally, the M525 features ENVE's patent pending, wide hookless beads that improve pinch flat resistance and allow riders to run modern lightweight XC tires with a reduced risk of pinch flatting or impact damage.

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.
