Road riding has never been this much fun. That's because the redesigned Ultegra ST-R8170 Dual Control Levers have all-new ergonomics, even more precise brake modulation, and wireless electronic shifting. This trifecta lets you focus on the next sprint, the next descent, or the next joke from your riding partner. Shimano's new Ultegra ST-R8170 brake levers bring enhanced modulation and control to every ride by employing Shimano's proven SERVO WAVE technology. The all-new Di2 platform, used on both Dura-Ace and Ultegra, untethers the shifters while delivering the world's fastest, most reliable wireless shifting. Your time on the bike is precious, let Shimano make it even better. 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. Please Note: this model is for the Shimano Ultegra R8170 Di2 12 Speed Disc Shifter only - the hydraulic brake caliper is sold separately.
Keeping your ride under control in all road cycling situations, this set combines an Ergopower Super Record 12 Speed Disc Brake controller and a brake caliper for a more ergonomic, more precise, more powerful and easier to maintain set-up. Benefitting from many of Campagnolo's finest technologies including Vari-Cushion, One lever-One action, AMS Adjustment and an Ultra-Shift System, this model also offers a wide range of features and customisation for fine-tuning your braking and shifting performance. 12 Speed Ergopower Super Record Disc Brake Controller The mechanical controller for the Ergopower Super Record 12x2 Speed Disc Brake offers an ergonomic, comfortable and safe support and grip thanks to Vari-Cushion technology, essential for those who stay on the saddle for several hours. The controls' inner workings are a concentration of technology and experience, starting with the "one lever-one action" function, which assigns each lever a single function, helping avoid shifting errors at tired or distracting moments, and then continue with the multiple shifting options which allows up- or downshifting by up to 5 sprockets at a time thanks to the Ultra-Shift mechanism. This function allows you to maintain cadence even in case of sudden changes of incline or rhythm, with speed and ease as useful as it is surprising. Further useful features are the levers' adjustability, which, thanks to Reach Adjustment, enable a low grip on the brake lever, helping those with smaller hands; and AMS Adjustment, which enables braking power modulation, using the dedicated adjusters. The Super Record Disc Brake levers are engineered with a double curvature for improved grip and are lightened with two slots that are added to the one dedicated to Reach Adjustment. Campagnolo Caliper The flat-mount Campagnolo brake caliper ensures powerful, modular braking in any situation owing to pistons measuring 22mm in diameter. The pad return is now optimised to ensure that there is no friction when the brake lever is released. A special metal plate positioned between the pad and the caliper piston cushions the vibrations during braking. The Campagnolo brake caliper is designed to be mounted together with the disc chosen by the rider (available separately) and to always guarantee the highest level of performance. Careful attention was given to making maintenance and assembly operations easy: the pads have wear indicators and replacing them is facilitated by the absence of physical return springs. Additionally, work was done on the insertion of the disc in the caliper to make changing the wheel easier and faster. Technologies: Controller Technologies Comfortable Body: The controls enable a solid, safe grip when pedalling out of the saddle or gripping high on the handlebar. Rapid Shifting: Immediate shifting engagement enables activating the front derailleur with minimum effort and in any hand position on the bar. Multiple Action: An unplanned ascent, a sudden jerk: it takes barely a moment to find the right ratio owing to the multiple action of the controls. Ergonomic: The shape of the body and the possibility to adjust the reach enable all cyclists to use these controls, regardless of the size of their hands or fingers. Customisable: 3 levels of reach adjustment. Upshifting Lever Integration: More space under the control body when gripping the Ergopower control. Disc Caliper: Flat mount disc only, to be compatible with the latest frame technology. Maximum Smoothness Cables: Updated cable set maintains exceptional smoothness far beyond those of the competition, maximum performance longevity. Superior Alignment: Braking lever pivot aligned with slant of ergo power, more efficient power transfer requiring less energy from rider's hand. Upgraded Brake Lever: The result of meticulous studies (double curve brake lever, updated form outward curve). Vari-Cushion Hood: Different thicknesses allowing for greater grip, comfort and water dispersion. Enlarged Shifting Paddles: For instant reaction access. Ultra-Shift System: Up to 5 sprockets in downshifting, up to 3 in upshifting. Caliper Technologies Standard Flat Mount: Fully compatible with flat-mount frames. 22mm Pistons in Phenolic Resin: Braking force and thermal isolation. Piston-Caliper Connector: The return action of the pistons is now optimised, rapidly returning the pads to their position and thus ensuring an overall clearance between pad and disc of 0.4-0.8 mm, with no risk of accidental contact. Interchangeable Spare Parts: Pads, cylinder, screws, bolts (same for all calipers): Fully compatible and optimised spare parts, making maintenance practical. Wear Indicator: It is very easy to see when the pads need to be replaced. Rounded Brake Pads: These facilitate disc insertion and speed up wheel changing. Anti-Vibration Plate: Optimal braking without vibrations. Two Fixing Screws: Rapid installation and maintenance.

Shimano Ultegra R8170 C50 Carbon CL Disc WheelThe Shimano Ultegra R8170 C50 Wheel features a 50mm-deep full carbon tubeless ready rim with Shimano D2 rim profiling. This rim offers exceptional aerodynamic efficiency and agility while maintaining stability and control during strong cross winds. Suited to climbing sessions, long-distance fast events and epic endurance rides, this wheel features a centre lock disc rotor mount and is compatible with Shimano 11 and 12-Speed drivetrain systems.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 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 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 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. Rear Wheel OPTBAL Spoke SystemThe 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 Shimano RS710 C32 disc-brake rear wheel is a great option if you’re looking, either to upgrade your bike’s wheels one at a time or if you simply need a spare. If it’s a full wheelset you’re looking for check out the RS710 C32 wheelset The famed Japanese-component makers have used this series to introduce their most affordable, carbon, road wheel ever. That being said, while it might be a more budget conscious option, that’s not to say its lacking in quality. As is the norm with Shimano’s mid-tier products, this wheel benefits from the technological advances that have been striven for in the production of their top-tier products. The end product is a wheel that’s impressively light—considering the price point—but also incorporates some of the aero-optimisation you’d expect of a modern wheel. Climbing Excellence The Shimano RS710 C32 rear is the perfect for those days spent climbing in the Alps. Weighing a respectable 839g, while there might be lighter wheels out there, at this price point it represents excellent value. In terms of design, the styling has been kept sleek and minimal. This is a stylish hoop in its own, but being so simplistic in its design it will also pair well with a number of other wheels without looking too out of place. Wider Rim, Better Braking As has become the norm in modern wheels, the RS710 C32 has been engineered to be wider than it might have been in the past. The hooked-rim profile is designed to optimally seat a 25mm to 32mm, tubeless tyre. Using a wider, tubeless tyre means you can run your tyres at lower pressures. For the traditionalists, used to pumping up 23mm tyres to 120psi, this might be something of an adjustment. But, rest assured, the accepted wisdom today is that the lower-pressure-wider-tyre combo is faster and more resilient to punctures. The RS710 C32 rear wheel has been engineered for hydraulic disc brakes; the benefits of which are numerous. With the latest disc brake technology, you’ll have consistent stopping power in the wet and on steep and/or long descents. Whether you’re in need of a replacement rear carbon wheel or an upgrade, the Shimano RS710 C46 is an aero-optimised, reliable option. Product Features 32mm rim depth Weight: 839g Internal-rim width of 21mm External-rim width of 28mm 24 spokes, bladed and butted Tubeless Ready Disc mount: Center-Lock 140 mm disc brake rotor compatible Recommended Tyre Size: 25-622—32-622 Pawl and Ratchet Engagement
The Shimano RS710 C46 rear, disc-brake wheelset is an aero-optimised performance wheel. It’s perhaps the Japanese-component maker’s most affordable carbon wheel for the road, ever; but that’s not say it’s lacking in performance characteristics. In their usual fashion, Shimano have drawn on their design and engineering expertise honed in manufacturing their top-tier Dura-Ace and Ultegra lines, to produce a set of wheels that offers an excellent balance between aerodynamic advantage and weight. In short, this is a great all-rounder option. If it’s a complete wheelset you’re looking for, check out the RS710 C46 wheelset. The All-Rounder As the name suggests, the Shimano RS710 C46 rear has a 46mm-deep rim. At this depth, it’s clear the rim is meant for speed. However, at 893g it only comes with a slight weight penalty compared to its shallower sibling, making it an ideal all-rounder. Whether it’s for fast bunch riding or rides over mixed terrain, this is an excellent option. Wider Rims, More Speed Cutting-edge component makers that they are, Shimano have produced a wider rim than we might have expected in the past. Boasting a 21mm-internal rim width, the C46s will seat a 25–32mm tyre, which can also be tubeless. This offers a number of benefits to slimmer tyres. For one, a wider tyre will work more effectively at lower pressures, which improves comfort and grip, as well as reducing rolling resistance. Ultimately this translates to more speed for less effort. And, who could complain about that? The Shimano RS710 C46 rear uses hydraulic disc-brakes. Using the latest disc-brake technology you’ll have access to the consistent stopping power afforded by these systems. Whether it’s wet or dry or you’re descending long and/or steep mountains, you’ll have confidence in your stopping abilities. Of course, the rear wheel is the hub of it all, literally. For this edition, Shimano have retained the cup-and-cone style bearings for the hub, common across much of their range. It’s a simple and reliable system, which has been tried and tested for a number of years. If it’s a carbon, all-rounder rear wheel, that’s at the more affordable end of the spectrum you seek then the Shimano RS710 C46 is the well-worth consideration. Product Features 46mm rim depth Compatible with 11- and 12-speed Weight: 893g Internal-rim width of 21mm External-rim width of 28mm Spoke count: 24 front and rear Hub design: cup and cone Pawl and Ratchet Engagement Tubeless-tyre compatible 11- and 12-speed
