We proudly present Fulcrum's newest member of its Racing family, with an extension of its already wide selection of disc brake specific wheelsets. The Fulcrum Racing 3 DB represents the newest and perhaps most versatile wheelset to date. Its aluminium construction and performance design make it a surprisingly efficient and reliable wheelset, sure to please no matter where it is put to the test. While the Fulcrum Racing 3 DB can certainly be used for pure road racing, it excels in road endurance and gravel, making it an extremely versatile all-around wheel. Performance does not always require rigidity and for endurance or gravel scenarios a more comfortable and compliant wheelset translates to better riding. The Racing 3 DB’s construction allows it to be 25% more comfortable than the pure road racing specific Racing Zero for example. Lower tyre pressures, bigger tyre dimensions, better grip, wider rim structure, increased comfort and better braking make for a long list of advantages that only a performance wheelset can bestow upon ride quality. The criteria for performance around this very versatile wheelset might be different but there is no denying that it is performance oriented but with a valuable dose of extreme versatility included. There are few better choices for the cyclist looking for the right tool for the job. The 1660 gram Racing 3 DB oddly enough is the right tool for many different jobs.

Zipp’s 303 S Tubeless Disc Brake wheelset provides today’s cyclists the versatility they demand with the speed they crave. Expanding greatly on its heritage of conquering the Spring Classics this 303 wheelset maintains its ideal-for-every-terrain 45mm rim depth but adds a significantly wider internal width to provide greater performance and ride quality in almost every measurable way. Road bikes are more versatile than ever no matter the road surface but just as fast as before. The 303 S offers an entirely new rim profile and design to optimize rider performance on this new breed of bike. This wheelset is tubeless for disc-brake bikes allowing the ability to run wide tires at lower pressures for race-ready speed on or off the pavement. The 303 S is among our lightest wheelsets optimized for top aero performance with a 28mm tire but capable of handling gravel tires up to 50mm wide. The 303 S borrows design concepts from the higher-level 303 Firecrest Tubeless Disc-brake wheelset to gain speed through increased efficiency. That is achieved by creating a wheel with reduced: Wind resistance rolling resistance rider fatigue and weight. The key innovation is in the 303 S Series’ rim design. Its 45mm rim depth is the same as its predecessor the 302 Disc brake. But its rim width is 2mm wider at 27mm and its tire bed is a full 7mm wider at 23mm. That rim platform is designed to be the fastest with a 28mm tire. The wide rim optimizes tire profile to allow lower tire pressure. That helps to reduce rolling resistance and provides a more compliant ride. The result of all this is a 10 percent watt savings vs. a top peer wheel in total power required to ride 40kph on a smooth flat road with a 28mm tire according to internal Zipp testing. This groundbreaking wheelset also features all-new cosmetics setting the rider apart from the pack and comes at an attractive price. FEATURES Zipp graphics and cosmetic identity that scream speed Fastest with 28mm fits wide gravel tires as well 76 / 176 DB hubs with Center locking interface XDR driver body option Wide rims optimize tire profile to allow lower tire pressure especially with tubeless. The result is a larger contact patch for increase grip for confident cornering descending and handling in wet conditions. Lower tire pressures and larger volume provides a compliant ride with fewer vibrations. Significant watt savings when running larger tires at lower pressure. Wide hookless rims create a seamless transition to the tire reducing drag.

Road riding has never been this much fun. That's because the redesigned Ultegra ST-R8170 Dual Control Levers have all-new ergonomics, even more precise brake modulation, and wireless electronic shifting. This trifecta lets you focus on the next sprint, the next descent, or the next joke from your riding partner. Shimano's new Ultegra ST-R8170 brake levers bring enhanced modulation and control to every ride by employing Shimano's proven SERVO WAVE technology. The all-new Di2 platform, used on both Dura-Ace and Ultegra, untethers the shifters while delivering the world's fastest, most reliable wireless shifting. Your time on the bike is precious, let Shimano make it even better. Servo Wave Precise Braking Control When you pull a Servo Wave brake lever, initial pad travel is fast, so little lever movement is needed to bring the pads into contact with the rotor. The power multiplication factor then increases rapidly at the pad-to-rim contact so more of the lever stroke is used to apply greater braking power with improved control. Shimano DCL Dual Control Lever DCL stands for Dual Control Lever. It has brake and shifting functions in the system and enables easy operation. Ergonomic innovation is as critical to higher standard performance as the added gearing. The shift internals borrows the robustness from Shimano's MTB technology and is so smooth and effortless that one finger shifts front and rear are possible. Indeed, shifting is the ultimate act of Shimano Total Integration and simply has to be experienced to be understood.

Zipp never fail disappoint with their wheels, and the Zipp 303 S disc rear wheel is no exception.

They blend aerodynamic advantage and weight excellently to ensure you're able roll along in the bunch effortlessly and don't feel bogged down when fighting against gravity. Wider and Faster The current trend is for bike rims to be wider than they traditionally were. The benefit of wider rims is they'll seat wider tyres, which in turn means you need a lower pressure to fill the tyre. Combined, this adds up to a smoother ride, more grip while cornering, and quicker rolling tyres. What's not to like?
