Please Note: This product page is for the Crankset only, chainring sold separately. Technologies: Providing the best balance of stiffness, strength, weight and rotating performance The concept of HOLLOWTECH II technology is focused on producing a superior crankset which will maximize a rider’s power transfer. The rigidity of the crankset ensures pedaling efficiency while its weight, a key element of the crankset, you want light, aids in cycling longer distances over which the rider needs to pedal more. Naturally, SHIMANO strove for the optimum balance between the conflicting needs of stiffness while producing a lightweight crank. HOLLOWTECH technology is an ultra-lightweight hollow crankarm created by SHIMANO with the company’s own proprietary forging technology that also maintains rigidity. The addition of HOLLOWTECH II technology integrates the bottom bracket axle with the right crankarm for more stiffness and a weight savings to achieve a high-dimensional balance. Its outboard bottom bracket bearing system provides better weight distribution and more pedaling stability, allowing for more efficient power transfer. The HOLLOWTECH II crankset has been developed by pursuing the optimum balance of stiffness & rotating performance in a lightweight and beautiful crankset design. High Precision Sealing Moreover, HOLLOWTECH II crankset has a high-precision sealing in the bearing area to increase durability maintaining the excellent rotating performance for long periods.
Building on what it learned with its Gen 2 Version, Stages has developed its technology even further for this latest Gen 3 model. Installed onto a Shimano Ultegra R8000 non-drive side crank arm, it 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 on the Stages G3 Ultegra R8000, Stages Cycling 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. Stable Connection Stages have made additional improvements to the Bluetooth and ANT+ transmitters and the accelerometer. This ensures the Stages Cycling Power Meter G3 l Ultegra R8000 provides a stable and powerful connection with your cycle computer is maintained and a faster sampling rate for more up-to-date feedback on your performance. Compatibility: · Compatible with all Shimano Hollowtech II road drivetrains · Frame Compatibility: Most frames · Device Compatibility: ANT+, Bluetooth Smart ready · Software Compatibility: StagesLink, Training Peaks, Strava, Garmin Training Centre and other In The Box: · Power meter · High-quality CR2032 coin cell battery · Product identification card with serial number and ANT+ I.D. · Number user guide
Balancing aerodynamics, weight, and affordability, the new Ultegra R8170 C50 wheelset is sure to inspire action on your group ride with its all-new tubeless carbon rim and updated, 12 and 11-speed compatible hub. Summiting climbs, carving descents, or cruising the flats, the new C50 is the jack of all trades among the new Ultegra R8170 wheel lineup. The tubeless, carbon rim features a 21 mm internal width that pairs nicely with wider, modern tires while the HYPERGLIDE cassette body is compatible with 11 and 12-speed cassettes. 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 tire 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.
Ready for blasting across mixed terrain conditions, this stunning model features a solid aluminium crankarm construction. This makes it ideal for pedalling over rock gardens, tree roots and debris as it's engineered to withstand even the most aggressive of riding conditions. Coming equipped with Shimano's Hollowtech II technology, this fantastic version provides the perfect balance of strength, weight and rotating performance, so you can enjoy maximum power transfer as you race for the podium. Lightweight 12 Speed MTB Crankset Powering you across every inch of the mountain, this sturdy component is also kitted out with a high-precision sealing in its bearing area. This increases its durability and longevity, so you can enjoy longer-lasting efficiency as you soar from the top of the hills to the forest floor. Weighing in at only 511g (approx.), this superb model allows you to benefit from optimum balance without adding any unnecessary grams to your ride.

The completely redesigned rim for the Campagnolo Zonda C17 road wheels takes its design inspiration from the growing trend that sees the use of increasingly wider tyres, with 25mm clinchers becoming the standard if not the new minimum sizing for road riding and racing. With this increased popularity of both 25mm and 28mm tyres, the wheel needs to be designed in a way to optimise the tyre/wheel interface. The updated wider rim on the Campagnolo Zonda C17 wheelset ensures a more efficient shape of the tyre, improving cornering grip and safety while reducing aerodynamic drag and rolling resistance. This seemingly small increase in width offers a surprisingly different riding experience, one that is sure to leave any cyclist pleasantly convinced that this change is for the best. The C17 rim has also been structurally optimised and ensures a surefooted grip on clincher tyres, as well as even better braking, feel when compared with previous versions.
