Zipp Zipp 303 S Carbon Disc Rear Road Wheel - Black - Shimano/SRAM}, Black
  • £519.99

Zipp 303 S Carbon Disc Rear Road WheelTaking its design from the higher-spec Firecrest 303 model, this rear wheel is ideal for modern "go anywhere" road bikes. Zipp has also updated this model with a wider rim to improve rider comfort, handling and aerodynamics. Expanding greatly on its heritage of conquering the Spring Classics, this 303 wheel maintains its ideal-for-every-terrain 45mm rim depth. However, this model 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 optimise rider performance on this new breed of bike. This wheelset is tubeless compatible and designed for disc-brake bikes, allowing the ability to run wide tires at lower pressures for race-ready speed on or off the tarmac.45mm Deep Rear WheelThe 303 S is among Zipp's lightest wheels, optimised for top aero performance with a 28mm tyre but capable of handling gravel tyres up to 50mm wide. The key innovation is in the 303 S's rim design. Its 45mm rim depth is the same as its predecessor, the 302 Disc brake. But its external rim width is 2mm wider, at 27mm, and its tyre bed is a full 7mm wider, at 23mm internal width. That rim platform is designed to be the fastest with a 28mm tyre. The wide rim optimises tyre profile to allow lower tyre pressure. That helps to reduce rolling resistance and provides a more compliant ride. The result of all this is a 10 watt savings vs. a top peer wheel in total power required to ride 40kph on a flat road with a 28mm tyre, according to internal Zipp testing.This ground-breaking wheel also features all-new cosmetics, setting the rider apart from the pack, and comes at a very attractive price.Please Note: Shimano/SRAM freehub option is for 11 speed Shimano/SRAM XD cassettes. The SRAM XDR freehub option is for 12 speed SRAM XD road cassettes.Features: Rim Material: Carbon Fibre with updated Zipp graphics Brake Compatibility: Disc (centre lock) Rim Inside Width: 23mm Rim Profile: Symmetrical Rim Type: Clincher Rim Finish: UB Fibre / Bake-on Labels / Matte Clear Coat Spoke Type: CX-Sprint Spoke Count: 24 Spoke Pattern: 2-cross Nipple Material: Brass Axle Type: TA 12x142mm Bearing Type: Cartridge - Stainless Steel Driver Mechanism: 3 pawls leaf spring Tubeless Ready: Yes Hub: 176 DB hub with centre locking interface Single or Pair: Single Brake Compatibility: Disc brake Weight: 819gBuy Zipp Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.

  • RRP £555.00
  • Saving you £5

Favero Assioma DUO-Shi Power MeterThis high-quality power meter is engineered for accuracy and consistency, whether you're training for an event or trying to beat your personal performance goals. It features an aerospace aluminium alloy construction, which makes it tough and dependable as you tackle every mile of road. Favero has also ensured that each power sensor is protected by a bi-component resin block that's extremely resistant to shocks and completely waterproof. Another highlight is it's simple to install and move from one bike to another just like your normal pedals. You can do it easily and without extra tools or the need for a mechanic.Dual-Sided Power MeasurementSpecifically designed for use with Shimano pedal bodies, this model is compatible with Shimano PD-R8000, PD-R7000, PD-6800, PD-R550 and PD-R540. It features power sensors for your right and left pedal to offer real dual-sided power data by measuring power individually for both legs. This makes it possible to observe with accuracy not only Total Power, but also L/R Balance, Torque Effectiveness (TE), Pedal Smoothness (PS), etc. Assioma also guarantees accurate and consistent data in all conditions on the road, and at any temperature ranging from -10°C and 60°C, thanks also to the Automatic Temperature Compensation (ATC).Unlike others, the measurement of Assioma is not affected by errors related to very irregular pedalling (e.g. uphill sprints) or the use of oval chainrings. This is because Assioma can detect the actual instantaneous angular velocity during the whole pedal stroke, thus providing ±1% accuracy in any conditions. Not only in the lab.Bluetooth and ANT+ ConnectivityAssioma communicates with bike computers and smartphones (both Android and iOS) via Bluetooth and ANT+. Assioma is the only pedal-based power meter for road with integrated rechargeable batteries; a single charge ensures at least 50 hours of use.Please note: Compatible Shimano pedal bodies are sold separately.

Assioma DUO-Shi user manual.Technologies: Designed for the compatibility with Shimano road: Assioma DUO-Shi has been designed for Shimano road users, as it offers the opportunity to keep on riding with your current Shimano pedal bodies* without giving up on the trustability and precision of Assioma. Installation into your own Shimano pedal bodies: Installing Assioma DUO-Shi into your own compatible Shimano pedal bodies* is simple and quick. Compatible Shimano pedal bodies: Assioma DUO-Shi is compatible with the following Shimano pedal bodies: PD-R8000, PD-R7000, PD-6800, PD-R550 and PD-R540. Increased Q-factor?: The Q-factor of Assioma Look version is of +54mm, whereas that of Assioma DUO-Shi measures +64mm with the PD-R7000/R550/R540 pedal bodies and +65mm with the PD-R8000/6800. Despite an initial concern related to the increase of the q-factor, we decided to proceed with the project considering that body size (height, pelvis width, etc.) is a subjective factor contributing to determining which is the best q-factor for each one of us. A final, positive feedback from our beta testers has eventually validated the product. Easy to install: Install and move your Assioma from one bike to another just like your normal pedals. You can do it easily and without extra tools or the need for a mechanic. IAV Cycling Dynamics: Assioma provides advanced metrics called IAV Cycling Dynamics: IAV Power Phase and IAV Rider Position. These metrics, combined with the classic power data permit you to analyze in detail your pedaling technique and how your position on the bike influences performance. IAV Power and gyroscope: Unlike others, the measurement of Assioma is not affected by errors related to very irregular pedaling (e.g. uphill sprints) or the use of oval chainrings. This is because Assioma can detect the actual instantaneous angular velocity during the whole pedal stroke, thus providing ±1% accuracy in any conditions. Not only in the lab.
