The Inpower direct mount road crankset provides precise and comprehensive data to improve your pedal stroke performance. Whether you're competing, training or wanting to improve your riding, this stunning component provides all the tools you need to take your performance to the next level. This model measures your pedalling power in the left leg through two sets of opposing gauges in the axle for precise data metrics including power output, cadence, torque effectiveness and pedal smoothness. Powered via standard AA battery, this state-of-the-art model lasts up to 300 hours and all of its electronics are housed inside a special sealed water-proof axle for centred rotational weight and maximum device protection. This is a powered tool for measuring your unique pedalling biomechanics via the Rotor Power application. Access real-time performance rich data including proprietary metrics Torque 360, Optimum Chainring Angle (OCA) and a recommendation of your Optimal Chainring Position (OCP). Combine this key information with Q RINGS oval chainrings to adjust your OCP in 1 of 5 different positions for fine-tuned pedalling efficiency and maximise transmission of power in your unique pedal rotation. Easily connect to your smartphone or cycling device via Bluetooth Smart or ANT+ and export your data for training analysis with various programmes such as TrainingPeaks.com. Thanks to its direct mount technology, a clever spline interface between the crank arm and chainrings provide superior stiffness and direct transfer of your pedalling torque. This is the perfect choice of upgrade for taking your training sessions seriously while also improving your overall performance in races and competitions.
With a shallow-depth aero profile and lively acceleration, the Ultegra R8170 C36 wheelset 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 wheelset is an upgrade for any road bike. Centre-Lock Disc Rotor Mount The 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 Profile Aerodynamic 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 System The 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. Rear Wheel OPTBAL Spoke System The OPTBAL rear wheel spoke system features 21 spokes—14 on the drive side and 7 on the non-drive side. Cassette spacing in today’s wheels produces unbalanced tension in traditional 1:1 spoke systems. This unbalance is intensified with the 11-speed cassette, producing nearly double the tension on the drive side spokes. Generally, high and low tension spokes have respectively tendency toward breaking down and coming loose spoke nipples. Unbalanced tension affects durability and strength. The OPTBAL design rebalances spoke tension, enhancing wheel rigidity and strength for a more durable wheel.
The hubs on the Shimano Ultegra RS700 C30 wheels feature high-quality contact seals and the legendary, highly adjustable Shimano cup and cone bearings that provide silky smooth rolling prowess and consistent performance. The rear wheel has been laced together using the Shimano OPTBAL 2:1 spoke lacing pattern. This means the drive side has twice as many spokes as the non-drive side and dramatically increases stiffness and rigidity, which is very noticeable when sprinting and powering out the watts.
Built on to a Shimano's top-of-the-line Dura-Ace R9100 non-drive side crank arm, the Stages Gen 2 sensor is individually calibrated to ensure its accuracy. Stages produce power meters that both avid amateurs and professionals at the top of their game can trust. Reliable Readings In All Conditions To ensure consistency of measurement, Stages introduced a world-first feature to its power meters. This feature is called “Active temperature Compensation” and it is built in as standard to account for sudden temperature changes, which if not accounted for, would result in false and inaccurate data.
These Fulcrum Racing Zero Competizione road bike wheels feature a durable aluminium rim construction, which allows them to handle all the challenges that are associated with road racing. Fulcrum has also gone the extra mile by equipping it with aluminium spokes and nipples, which give it an extra layer of robustness as you race against your competitors. Kitted out with a carbon fibre front hub, this wheelset allows you to benefit from its incredible strength-to-weight ratio on every mile. This attention to detail makes it an ideal choice of upgrade for performance-driven riders who want to save every gram on their road bike.
With patented lightweight aero spokes and a 19mm internal rim width, this road bike wheelset is lightweight and very durable. It features a rock-solid aluminium maxtal rim construction with renowned Fore technology, which makes it laterally stiff, vertically compliant and more dynamic on every stretch of road. Mavic has also equipped this model with rim brake compatibility with a UB Control brake track, so you can enjoy smooth and dependable braking performance wherever your journey takes you. Coming complete with UST tubeless technology, this road-ready wheelset delivers greater stability, comfort and less chance of flats. Lightweight Road Bike Wheelset This model is lightweight (100g lighter than the former Ksyrium Elite despite its wider rim) and durable as ever thanks to Mavic's patented ISM4D technology. This manufacturing process removes all excess material between each spoke hole while keeping the rim wall thick enough where spoke tension and stress is the highest. Made in France, in the brand's aluminium rim factory, its double-butted spokes further reduce weight while making each wheel more responsive. These spokes also have a patented elliptical shape that can save 5 watts for added efficiency. Fore Tapeless Tubeless Technology This wheelset's stiffness is optimised thanks to Fore technology. The upper bridge is not drilled, so it remains strong and rigid and doesn’t require the use of rim tape (another 30g saved per wheel). The rim bed’s updated shape makes it easier than ever to mount and remove tyres, and Mavic's UST Tubeless technology improves rolling resistance and grip while reducing the risk of punctures. The Infinity hub platform also optimises stiffness and power transfer with highly controlled spoke tension, while an Instant Drive 360 freewheel coupled with automatic bearing preload adjustment (QRM Auto) delivers fast engagement and durability.
