Tour Proven Stages Power has carried riders to three consecutive Tour de France victories, plus many more world and national championships. If you believe racing provides the world’s best product proving ground, then Stages Power is proven as the world’s best power meter. Active Temperature Compensation as standard equipment Consistency of measurement is the most important feature of a power meter. Stages Power was the first meter to make temperature compensation an automatic process ensuring accurate readings no matter the environmental conditions. ATC is the key reason a rider can trust data from Stages Power in all conditions. Individual meter calibration for the most accurate results Each Stages Power meter is calibrated individually to ensure a +/- 1,5% accuracy level, which is an industry best for non-scientific power meters. Individual calibration means that you can trust the bi-lateral data produced by our system, as it's a real measurement and not an estimation. Stages Power R drive-side meter for added compatibility or upgrading an existing Stages Power L meter to Stages Power LR While not widespread there are some key bicycle models that are not compatibile with the non-drive crank arm based Stages Power meter because of interference with the power meter housing, for example Cervelo's P5 and many bikes with chainstay mounted brake calipers. Stages Power R offers increased compatibility with these models as well as the ability to upgrade existing Stages Power L power meters to Stages Power LR (dual) meter systems. Features: Active temperature compensation Accelerometer based cadence measurement or the option to use a Hall-Effect based system with magnet Wirelessly upgradable firmware LED indicator for visual indication of battery levels and zero reset confirmation without connected app or headunit Updated accelorometer and addition of gyroscope for improved cadence resolution NFC tap to pair for some phones and devices Upgraded BLE and ANT+ radios offer a 6x improvement of data transmission strength Specifications: Accuracy: +/- 1,5% accurate in all conditions Power meter housing: low profile design, with robust door interface.

Shimano Ultegra R8170 C36 Carbon CL Front Disc WheelThe Ultegra R8170 C36 Carbon CL Disc Wheel from Shimano is the ideal aerodynamic and Tubeless Ready road race wheel for steep climbing events, fast sprints and versatile all-day riding performance. Full carbon rim construction with Shimano D2 rim profile and a centre lock disc rotor mount, this top-tier road bike wheel is stiff, flex free, aerodynamically optimised, will ensure exceptional braking efficiency in all weather conditions.With a shallow-depth aero profile and lively acceleration, the Ultegra R8170 C36 front wheel is a climber's delight that delivers performance every road rider will appreciate.With the speed and efficiency of tubeless tyres, the everyday performance of a shallow, aero profile carbon rim, and the convenience of 11 and 12-speed compatibility, the new Ultegra R8170 C36 front wheel is an upgrade for any road bike.Centre-Lock Disc Rotor MountThe Centre Lock system makes an easy rotor installation possible with a spline mount and a lock ring. The lock ring mounting system reduces the total working hours by shortening the amount of time of both installation and de-installation. In addition, the secure fixing by the spline mount enhances precision and rigidity while improving braking efficiency.D2 Aerodynamic Rim ProfileAerodynamic performance is affected by wind direction. To create the D2 rim, Shimano engineers considered both frontal and crosswinds, aiming to achieve optimal performance in real-world riding conditions. Extensive prototype testing, in the wind tunnel and on the road, proved that a wide rim shape with a deep tyre bed performs best across a wide range of conditions. At yaw angles ranging from 0 to 15 degrees, the Shimano D2 rim profile reduces air drag better than others aero shape rims. This rim design also boosts lateral wheel stiffness and offers improved vertical compliance for increased control, comfort and durability on the road.Shimano E-Thru Axle SystemThe tool-less type thru-axle skewer system optimizes rigidity and weight balance and enables easy operation with a reliable internal cam mechanism. The 15 mm thru-axle system is 15% stiffer torsionally and 25% stiffer in transverse shear than a traditional 9 mm quick release front axle system. High rigidity is secured while keeping the optimum weight balance. The E-Thru axle hub system minimizes the distortion of suspension while maintaining lightweight for riding around sharp corners at high speed.Features: Series: Ultegra R8100 Series Rim: Carbon Tubeless Ready Type: Clincher 36mm height full Carbon rim Internal Rim Width: 21mm Shared rim profile with R9200 Dura-Ace wheels Improved aerodynamics Axle: 12mm E-THRU Disc Rotor Mount: Centre Lock Single or Pair: Single front wheel Weight: 657gA 2-year warranty is offered with all Shimano products from Chain Reaction Cycles (3 years on Dura-Ace and XTR products).Buy Shimano Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.
