Reliable, simple, and e-bike specific hub. To withstand the higher torque of e-drive systems, the 350 hybrid is equipped with steel rotors and a specific 24T ratchet machined out of hardened steel. Oversized bearings ensure smooth running under extreme conditions.

Reliability meets simplicity—running smoothly day-in and day-out. The 350 hub was developed according to the credo: Reliability meets simplicity. The simultaneous engagement of the ratchets and the resulting large engagement area provide reliability. The plugged construction allows easy maintenance without the need for tools. Adaptation to different axle standards or modification of the engagement angle is also possible with just a few manual steps.

Made for the biggest tires, the cutouts keep the weight low. Fat bike rims must be strong, stable, and lightweight yet be able to accommodate very large tires.

The rim for high-impact riding. The BA30 is a quality alloy rim designed to withstand a real beating. This is the rim for high-impact riding when the trails are rough and rugged. With an internal bracing structure, the BA30 has torsional stiffness for directional control in demanding circumstances. The BA30 features a thick bead wall adjacent to the tire to resist impact deformation, with a wider, rounded top-edge to reduce sidewall cuts. The nipple/spoke bed is oriented to the spoke direction to reduce weakness caused by bend in the spoke at the nipple hole. The BA30 is made with premium alloy, extruded with an internal brace profile and carefully formed for consistent shape. It is then fusion welded and ground for a strong precise finish. Our fusion welding system leaves a perfect seamless joint that becomes the strongest section of the rim ensuring that your rim won’t split if you impact at the seam. - Premium extruded alloy - Fusion welded seam-ground finish - Internal bracing profile - Impact resistant design - Tubeless Ready - 27.5: 570g - 29: 610g - 27.5" ERD: 566mm - 29" ERD: 604mm

Zipp 101 XPLR MOTO Rim Strip And Tubeless Tape Kit (includes rim strip and tubeless tape for 1 wheel).

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)

Zipp's 303 Firecrest Tubeless rim brake wheels offer all-around performance for a new era of road riding. They're rich in heritage yet loaded with innovations; as adept in the mountains as on rolling hills, windswept farm lanes, or ferocious field sprints. At Zipp, we never rest on laurels. These wheels feature a 19mm internal width and are tubeless ready. That means you can run lower tire pressure for greater cornering grip and compliance while still benefiting from reduced rolling resistance and without the risk of pinch flats. When it comes to pure speed, the 303 Firecrest Tubeless packs a serious punch. They're lightweight and feature ABLC Sawtooth Technology, a complex dimpling pattern first developed for our top-level NSW wheel lineup. This technology helps to achieve the optimization of low aerodynamic drag and crosswind stability, which we call AeroBalance. The ShowStopper textured braking surface delivers unrivaled rim braking performance in wet or dry conditions. Lastly, at the center of the 303 Firecrest Tubeless rim-brake is a new versatile and durable hub, the German-engineered ZR1. - Tubeless for secure performance even when ridden at lower tire pressures - New ZR1 hub is engineered in Germany with better seal design for improved durability and quicker response with 66 points of engagement - Versatile 45mm rim profile that's fast, stable, and versatile - ABLC Sawtooth dimple design helps manage air flow around the rim, and contributes to create a faster, more stable wheel - Showstopper textured brake track delivers superior modulation and shortest stopping distances in wet and dry conditions - New Zipp graphics and cosmetic identity that scream speed - Ships with QR end caps, quick release skewers
