Wheels

Road bikes are going where they’ve never gone before, are expected to do more, and are being ridden harder than ever. At the same time disc brakes are rewriting the rules of what’s possible with rim design. For this new era, the Zipp 303 Firecrest Tubeless Disc-brake wheelset sets the new standard. With a disc-specific, tubeless rim, the 303 Firecrest Carbon Clincher is now internally 21mm wide and faster than ever. Designed from the start as a tubeless rim, the 303 Firecrest features a rim bed made with internal ridges to lock the tire’s bead in place, ensuring secure performance, even when ridden at lower tire pressures. A new carbon fiber layup keeps weight low while maintaining the 303’s legendary durability. The rim’s lightweight design allows the 303 to glide up the steepest climbs while SRAM's robust 77/177D hubset keep the wheels stiff and responsive. Each Wheel Includes: - Zipp Tubeless valve extender and valve-core wrench - Zipp rim tape (factory taped) - Zipp Tangente quick-release skewer - Zipp thru-axle end caps

Zipp's 353 NSW Tubeless Disc-brake wheel is the pinnacle of our pursuit of versatility and speed. This wheel fuses Zipp's two most advanced approaches, Sawtooth rim profile and TSE, for an all-encompassing approach to performance. With its undulating 45mm-deep rim shape, the 353 NSW provides speed on every terrain with best-in-class aerodynamic efficiency and crosswind stability. The 353 NSW is Zipp's lightest tubeless wheelset yet, making it a fast-puncher ready to fight its way into the breakaway. Zipp's use of a hookless (straight side) rim in the 353 NSW is integral to achieving our mission of Making You Faster. With hookless, the transition between the tire and the rim is more seamless and aero. Zipp's hookless rims have more efficient resin distribution, which means lighter wheels. They also are highly durable. Zipp's 353 NSW's Sawtooth rim shape with Hyperfoils optimizes aerodynamic efficiency and crosswind stability. The Sawtooth design also allows the rim to be structurally strong but light. That will help you snap out of corners and maintain that speed no matter the terrain, especially in the steep, punchy stuff. The 353 NSW utilizes Zipp's Total System Efficiency, or TSE, approach to wheel design: overcoming specific barriers to speed: wind resistance, gravity, rolling resistance, and vibration losses. The wheel's 25mm internal width is ideal for running wider tubeless tires at reduced air pressure for a more efficient ride. At the center of the 353 NSW is the Cognition V2 Hubset, re-engineered with an updated Axial Clutch V2 mechanism for quicker engagement and lower friction, as well as improved durability. - Versatile endurance wheel for the modern road bike with tubeless and hookless rim profile - Our lightest tubeless wheel yet, making it a fast-puncher ready to fight - Optimized tire bed for easy tire installation - TSE for greater efficiency and reduced rolling resistance - Sawtooth rim with Hyperfoil nodes and HexFin ABLC dimple pattern for top aero and crosswind-stable performance with an undulating rim depth - Cognition V2 hubset rolls efficiently whether you are pedaling or coasting.

Trainer Caps allow thru-axle bikes to be used with most wind, magnetic or fluid cycling trainers. Cold weather and short days are never far from a Minnesotan's mind so Wolf Tooth engineers created Trainer Caps to reduce barriers to winter workouts. Non-drive side axle caps are joined by drive-side plugs that can be installed or removed without tools to make the prospect of hopping on the trainer a little more bearable. - Compatibility: Wolf Tooth Rear Axles (not compatible with rear axles from other manufacturers) - Plug has O-ring retention – no tool required

Boostinators are hub specific conversions designed to take non-boost hubs and convert them to boost compatibility. Don't toss out that wheelset - Boostinate it.

The Wolf Tooth Rear Axle uses a captive steel washer under the head to reduce friction on the dropout face. This protects your expensive frame, transfers more of the tightening torque to clamping load for a stiffer interface and prevents the axle from sticking or galling when you want to remove it. - Made in Minnesota to aerospace standards

The Wolf Tooth axle uses a captive steel washer under the head to reduce friction on the fork leg. This protects your expensive fork, transfers more of the tightening torque to clamping load for a stiffer interface and prevents the axle from sticking or galling when you want to remove it. These are also a great replacement option for lost or damaged stock axles. Always apply a small amount of grease to the washer and threads when installing. - Designed and manufactured in Minneapolis, MN USA 7075 T6 Aluminum

Boostinator kits allow non-boost wheels to be mounted in Boost spacing frames and forks. While incremental, the benefits of the "Boost" 15x110mm front and 12x148mm rear axle standards are clear: better clearance for fatter tires & rims and reduced dish for stiffer, stronger wheels. The big bummer? Taking full advantage requires not only a new frame and fork, but new wheels as well. In response, we have developed the Boostinator. When paired with compatible 15x100mm or 12x142mm hubs, Boostinator kits allow existing wheels to be mounted in Boost-standard frames and forks. Disc and drivetrain positions are maintained and, thanks to a quick re-dish, spoke bracing angles are improved. Boostinator kits consist of a specially-designed axle end cap and, in the case of rear kits, a precision-machined rotor spacer with a set of six high-strength bolts. In keeping with Boost specifications, the disc and cassette are shifted outboard, allowing brakes and derailleurs to function as designed. Compatibility: - Front boostinators are only an endcap and do not require a rotor spacer. The wheel is re-dished. - Rear boostinators require both a re-dish and rotor spacer. - Rear Boostinator kits are not approved for rotors larger than 183mm. - Hubs spacing is 100mm front and 142 rear, and the Boostinators make them 110 and 148 respectively. - Compatible with 6-bolt FRONT wheels and SOME centerlock models. - Compatible with ONLY 6-bolt REAR wheels (there is no way to space centerlock rotors over 6mm). - NOT recommend (or safe) for non-symmetric lacing like the 2:1 lacing found on some of Industry Nine's wheels. *Note: You will need to re-dish your wheel after installing any Boosinator. Boostinator DR: - The Boostinator DR is compatible with DT-Swiss 12x142mm Star Ratchet (240- and 350-series) rear hubs with 6-bolt (IS) rotor mounts. - Centerlock hubs are not supported. - 180- and 190-series hubs are Centerlock only. - The Boostinator DR is also compatible with some complete wheels from DT Swiss, Roval (Specialized), Giant, Syncros (Scott), and others that use DT's Star Ratchet internals. - Remove the disc side end cap. Bearing size 6802 15x24. - Net weight: 18g Boostinator HR: - The Boostinator HR is compatible with 12x142mm Hope Pro 2 EVO and Pro 4 rear hubs. - Non-EVO Pro 2 hubs are not supported - Net weight: 18g Boostinator 9TR: - Compatible with 142x12 rear Industry Nine Torch hubs. - Not compatible with 2:1 lacing wheels from Industry Nine - Not compatible with Centerlock hubs Tech Specs: - Material: 6061 aluminum - Included: Rear kits come with appropriate-length Class 10.9 bolts, each roughly 40% stronger than more common Class 8.8 hardware.

E-bikes add to the riding experience by simply providing more for less. More distance, more laps, more climbs and more descents. With all those "mores" also comes more weight continually bashing on the components of an e-bike. In order to overcome the increased forces induced by the technological progression of modern e-bikes, we designed our HTZ rims with more material in every area of the rim prole. Every wall of the rim is 25-30% thicker in comparison to those on our standard rims, which we then paired with our proven I-Beam center support to ensure no beating was too great for these rims. All HTZ rims are TCS 2.0 tubeless, feature asymmetrical spoke drilling, and are available in widths ranging from i23 to i35 in order to provide options for e-bikes ranging from e-assist gravel bikes to dual-crown downhill bikes that no longer need a truck to be shuttled. FEATURES: - Capable of withstanding the forces of a modern e-bike. - 4D angled spoke drilling eliminates binding and lateral loading and disperses tension more evenly over a greater area. - Symmetric outer profile provides equal dissipation of impact forces on both sides of the rim while asymmetric spoke hole drilling allows for more even spoke tension and increased wheel strength. - Disc-brake only. - TCS 2.0 Tubeless ready and comes with a preinstalled Solid Strip, which lies beneath the tubeless tape and prevents sagging at the spoke holes, creating a smooth interface between the rim and tire bead. This prevents air from escaping around the bead and therefore requires less air volume and pressure to mount a tire. Solid Strip also protects the airtight tubeless system from being punctured in the case of a broken spoke. TCS 2.0 creates a more robust, easily installed, and dependable tubeless system.
