The right wheel and tire combination can improve your skills and upgrade the performance of your E-bike on challenging off-road terrain. The new E-Deemax S is built specifically for E-bikes and has some unique technologies to help you ride smoother and have more fun on the trail. Our patented PFP technology (Pinch Flat Protection) features rims with a wider contact surface at the top of sidewall to significantly reduce the risk of tire cuts and punctures. The 30mm wide rims allow you to run lower tire pressure for better traction and smooth rolling efficiency. Our patented Fore technology features a fully sealed upper rim bridge that eliminates the need for rim tape, making it the easiest system for mounting and changing tubeless tires ISM rim machining removes material from the rims in strategic areas to minimize weight without compromising strength, and our new Black Shield treatment protects the rims against impacts and scratches. We use 28 straight-pull spokes (same spoke length throughout) for a strong connection between the rim and hub, which has our ultra-reliable ID360 double ratchet system for quick engagement and acceleration. Set up for either 6-bolt or center lock disc mounts, these 29" wheels are available for Shimano HG9, XD and Micro Spline freewheel bodies and come with UST tubeless valves, spare spokes and accessories.

This lightweight aluminum wheelset is a no brainer for anybody looking to make an easy upgrade from OEM wheels. The Ksyrium S can significantly boost any bike's performance and is an easy entry point to Mavic quality that doesn't take any shortcuts. The Ksyrium S is 60g lighter than the former Ksyrium UST while also being wider, stronger and laterally stiffer. Stiffness is optimized using Fore technology. The upper bridge remains undrilled, optimizing strength and rigidity, and it doesn't require the use of a rim tape, which saves another 30g per wheel. The rim bed's new shape makes it easier than ever to mount and remove tires, and our UST Tubeless technology improves rolling resistance and grip while reducing the risk of punctures. Those rims are made in France, in our aluminum rim factory. Our new Infinity hub platform optimizes stiffness and power transfer with highly controlled spoke tension, while an Instant Drive 360 freewheel coupled with our automatic bearing preload adjustment (QRM Auto) delivers fast engagement and durability. The Ksyrium S doesn't just ride fast, it looks fast too. Matte painted hubs, invisible rim welding and deep black spokes give this wheelset a premium look that stands out from the crowd. It's available for Shimano cassettes, and can convert to Campagnolo or XD-Road with optional driver bodies.

Riding is believing with the Zipp 1ZERO HITOP SW MTB wheelset when it comes to making you faster. Trail compliance is vital, with modern cross-country races becoming rougher and more challenging. No longer is it good enough for an XC wheelset to be stiff above all else. Instead, a wheelset should feel alive. The 1ZERO HITOP SW carbon rim complies with the terrain thanks to Zipp's proprietary HITOP Technology for carbon layup. The result is a lightweight XC wheel that carries speed through all sections of the trail, rocks, roots, and ruts with the durability required for a trail bike with up to 130mm of travel.

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)
