Prime Primavera 85 Carbon Rim Brake Rear WheelWider = Improved PerformanceFeaturing an 85mm deep aero rim profile, this rear wheel offers more speed for the same effort and it's specifically designed for time trial (TT) and triathlon (tri) racing. Developed with Team Spectra in search of the marginal gains that could help them in some of the UK's biggest races, this model uses a wider rim profile to create a more linear contour with the tyre to increase the Primavera 85's aerodynamic properties.Greater Strength To Weight RatioBuilt up using a SR1, 36T Ratchet System, CNC machined 6061 alloy hub and DT Swiss straight pull spokes, this model creates a stiffer wheel with a greater strength to weight ratio and more reactivity. Its Star Ratchet hub also provides superior reliability, due to each of the ratchets engaging simultaneously every time. Prime has also ensured that tool free freehub conversion is possible. Coming kitted out with an incorporated notch, the newly developed shape of the end caps simplifies disassembly significantly and therefore makes maintenance even easier.Aero AdvantageIf you're looking for an advantage in your next TT or Triathlon event, the Prime Primavera 85 Carbon Rim Brake Rear Wheel is a perfect choice of upgrade to improve your ride.Lightweight RimPrime has experimented with numerous types of resin and tested countless new lay ups before they settled on the new and improved Primavera 85 rim.

Note: Listing is for a Rear wheel onlyZipp’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.Key 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.,. Specification:Orientation (wheels): Rear,Size (wheels): 700c,Rim construction: Carbon,Tire compatibility: Clincher Tubeless Ready,Rim depth: 45mm,Surface texture: Smooth,Brake compatibility: Disc (Center Lock),Rim - inside width: 23mm,Rim profile: Symmetrical,Rim finish: UD fiber / Bake-On labels / Matte clear coat,Color (Decal): Standard,Nipple material: Brass,Nipple anti-rotation: Sapim Secure-Loc,Spoke type: CX-Sprint,Spoke count: 24,Spoke pattern: 2 Cross,Hub: 176D,Color (hub): Black,Axle type (Wheels): TA 12x142,Axle material: Aluminum front & rear,Bearings: Cartridge - Stainless Steel,Driver Mechanism: 3 Pawls Leaf Spring,Driver body material: Aluminum,Max tire pressure: 73psi,Max recommended rider weight: 250lbs,.

All-new lever ergonomics on the Dura-Ace ST-R9270 dual control levers bring new levels of comfort and control to road cycling. With the fastest wireless shifting available and even more precise brake modulation, Dura-Ace redefines performance. Now featuring Servo Wave Action brake technology, the new Dura-Ace ST-R9270 brake lever delivers modulation and control like never before. Wireless shifting keeps your bike looking clean while offering the fastest, most precise gear changes available. All of this resides in a Dual Control Lever to employs the most advanced materials to offer lightweight and refined ergonomics that provide comfort and control for the most demanding conditions. 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. Shimano E-Tube E-Tube is Shimano's “service” that uses websites or apps to maximize the enjoyment of riding a bicycle by connecting the riders, the bicycles and Shimano.
