700c, 27-Inch & 650c

SPEED is synonymous with competition, and represents the ultimate in performance, above all when the stopwatch is the only means used to judge results on a racing bike. It the name of a product created for World Tour professionals, who use the tubular tire version, and for all those who use these wheels for racing. With the above as a premise, what features should the 40 mm-high, non-tubular SPEED wheel - which is ideal in most situations - have? That's simple: the best of everything. And thus, the SPEED 40 DB, 2-Way Fit (tubeless) + disc brake wheel is born. SPEED 40 DB is a set of wheels for use with disc brakes that will simply leave you speechless, featuring a cutting-edge rim with a new shape, designed according to innovative technical concepts. At 26.5 mm, the wheel is wider, with an aerodynamic shape which includes a pronounced 8 mm profile and a "twill" weave carbon fiber texture, optimizing the elastic responsiveness of the rim. The final aerodynamic profile is the fruit of a lengthy finishing process: from simulations to prototype testing, in order to select the best design whilst taking the side wind and the turbulence created by the disc into account, followed by a long analysis to choose the best materials to be used on the final product. Need a few more hints to get a real feel for the spirit of this wheel? Here they are: the SPEED 40 DB boasts a 2-Way Fit construction - and as such is tubeless by conception - with a 19 mm wide channel, and a USB ceramic cone & cup bearing system. And, of course, the oversize flanges on the hubs are designed to take full advantage of all the benefits offered by the disc brake. Ultimately, the SPEED 40 DB is the new point of reference for riders who have chosen to a disc brake, and who are looking for the very best wheels out there, with a true racing pedigree and a perfect mid-profile on the majority of routes.

Reserve wheels are built on the highest quality carbon rims on the market. Everything from the thickness of the rim beads to the external spoke hole reinforcements comes purely from experience of knowing what riders need at every level-from international racing to your local trails. - Built with standard high-quality components including j-bend spokes (28 count) and Sapim mechanically locking nipples - Ships with rim tape installed, tubeless-ready valves, and cards identifying the Santa Cruz builder of each of your wheels - Backed by a lifetime warranty - Built with DT Swiss Hubs

Reserve returns with the ultimate climbing wheelset; the 34/37 Turbulent Aero. Developed using Turbulent Aero data and technology, the 34/37 TA is designed to help get you up those mountain passes as fast as possible. Comparted to the original 34/37, the revised TA set is 30 grams lighter per rim, and 4 grams faster in the wind tunnel. And in keeping with Reserve workmanlike ways, you’ll find external nipples, standard spokes, no tire limitations with a semi-hooked design and no rider weight limits. - Designed to be your no fuss climbing wheelset. There are no weight limits, no tire limitations, and can be set up tubeless or with tubes - Mixed profile front and rear rims provide maximum stability, lowest weight and optimized aerodynamics - Internally reinforced spoke holes to strengthen the area where the rim sees the most force, around the spoke nipple. This provides for improved strength without adding unnecessary weight - Lifetime warranty supported by a no-fault crash replacement - Built with DT Swiss Hubs

Bringing cutting edge performance to the diverse needs of drop bar off-roaders, Reserve’s 40/44 GR gravel wheels are tailored for the demands of off-road exploration and gravel riding, but with an aero focus. Leveraging Turbulent Aero technology, the 40/44 GR features a 40mm front paired with a 44mm rear, establishing it as the fastest and most stable Reserve gravel wheelset to date. Wider than the previous gravel wheels to allow for tires up to 50c tires, the 40/44 GR plays nicely with today’s slew of big volume gravel tires and a semi-hooked rim makes tubeless set up easier than ever. - Designed to be your no fuss aero gravel riding and racing wheelset - Wider internal width of 27mm - Tubeless and tube compatible - Wide/low front mixed with narrow/tall rear for maximum stability, lowest weight and optimal aerodynamics - Internally reinforced spoke holes to strengthen the area where the rim sees the most force, around the spoke nipple. This provides for improved strength without adding unnecessary weight - Built with DT Swiss Hubs

Developed and tested using Turbulent Aero technology, the 42/49 is designed for everything you do, providing all-day capability with aerodynamic sensibilities. Raced at events as varied as the Paris-Roubaix and the Giro D’Italia, the 42/49 wheels have a lifetime warranty supported by a no-fault crash replacement. And in keeping with Reserve workmanlike ways, you’ll find external nipples, standard spokes, no tire limitations with a semi-hooked design and no rider weight limits. - Wind tunnel tested using Computational Fluid Dynamics (CFD), with the goal of maximizing aerodynamics while enhancing stability - Optimized carbon fiber rim construction allows Reserve to define the exact fiber orientation for each rim model, to maximize stiffness and strength without sacrificing weight - Built with DT Swiss Hubs

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 wheel yet, making it a fast-puncher ready to fight its way into the breakaway. Zipp's use of hookless (straight side) rims 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. Its Axial ClutchV2 technology reduces drag and lowers friction - Ships with 12mm end caps - Center Lock rotor interface. Lockring is included - Zipp graphics applied using Zipp's ImPress direct-print technology - Lifetime warranty
