Elite road racers demand reliable and precise shifting, 12-speed Dura-Ace R9150 delivers with its super-lightweight and compact design Synchronized Shift designed, developed to choose the next biggest or lowest gear ratio irrespective of whether a gear change needs to be made by the front or rear derailleur The Di2 front derailleur's operation is pioneering, smooth shifting is guaranteed thanks to wireless communication with the gear levers. What's more, shifting the rear derailleur automatically trims the front derailleur The biggest difference you will notice is just how much quicker and effortlessly smoother shifting on the front chainrings is, even under load The removal of traditional mechanical cables in favour of electrical wires not only eliminates poor shifting caused by contaminates, corrosion and stretching, but provides effortless gear shifts The front derailleur also trims automatically; the cage moves in response to the position of the rear derailleur on the cassette to ensure no chain rub and a quiet unobtrusive ride, enabling you to concentrate on the road ahead Braze-on fit as standard; if your bike does not have a braze-on mount seat tube adapters are available 12-speed E-tube SD300 wire compatible

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

Campagnolo have been producing the Zonda C17 for quite some time now, and there’s good reason for them being one of the company’s bestselling aluminum rims. At only 1540 grams, as a wheelset it’s respectably lightweight, but is also reliable, robust, and stiff. As one of the cheaper wheels offered by the iconic Italian brand, it’s an excellent choice for long winter base miles and commuting through all seasons. Lighter And Stronger For this version, Campy have shaved off 10 grams from the previous version, providing a more responsive ride feel. However, despite the weight loss regime, thanks to the inclusion of a milled rim and the choice of Mega-G3 lacing pattern, this wheelset remains strong and stiff. To further increase the wheelset’s durability, it’s been equipped with an alloy hub filled with steel bearings, meaning they’ll spin smoothly for season after season. Spoke To Me The Zonda C17 uses two different spoke counts on the front and rear wheel. On the front, 16 aero steel spokes are used to keep weight down. The rear uses these same spokes, but there are 21 in a 2:1 spoke ratio on the drive side to maximise stiffness. With this new wheelset Campagnolo have also widened the internal rim width, meaning this version of the C17 is optimised for 25mm and 28mm tyres. By fitting a wider tyre, you’ll not only have a more comfortable riding experience and more grip in the corners, but also the tyre-shape cuts through the air more efficiently. Certified Excellence As you’d expect from a brand with as much pedigree as Campagnolo, all Zonda wheelsets are built by a certified Campagnolo technician and are quality controlled by electronic systems, ensuring a high-quality build that lasts. In all, if it’s a durable, but lightweight wheelset you are a looking for that is ideal for training, commuting and general everyday riding then this is a great option.
