The Shimano 105 Di2 RD-R7150 rear derailleur is quite possibly the biggest advancement in 105 technology since the range was introduced. In its mechanical form, 105 offered excellent shifting performance; the introduction of electronic gear changing offers even quicker and smoother shifting than ever. With a 105 Di2 rear derailleur at your disposal, you’ll have access to lightning-quick, effortless gear changes at the click of a button. What Big Teeth You Have: The 105 R7150 rear derailleur comes with a greater range of gear capacity. Coming as 12-speed and capable of handling a 36T cassette, it’s the perfect rear mech for tackling those big days out on the bike. Pair it with a compact chainset up front and there’ll be very few mountains you won’t be able to tackle. Such a broad range of gears will have you confidently tackling steep climbs, taking on bikepacking adventures, or getting stuck into fast bunch rides. From The Shadow: Similarly to Shimano’s top-tier lines—Dura-Ace and Ultegra—and drawing on the company’s mountain bike ranges, the 105 Di2 rear derailleur uses the “shadow” design. This design is intended to increase stability when shifting on rough roads and under load. With such technology you can be confident when changing gears on those steep inclines and when caught out in a race. What’s more, the shape created from this design is sleek and compact, reducing the risk of damage in the event of crash and increasing your aerodynamic advantage. Wireless Indicators: Though the 105 Di2 rear derailleur is compact in its design, it’s still chocked full of technological wizardry. It includes an integrated wireless unit that, in conjunction with the shifters, offers seamless gear changes free of cables. Handily, the derailleur features LED status indicators to let you know: battery status, when the unit is paired, and when it is in adjustment mode.

The introduction of Di2 to Shimano’s 105 front derailleur represents a dramatic leap forwards for the Japanese brand’s most popular groupset. Even in its mechanical form, a 105 front mech offered smooth, precise gear shifts; the addition of Di2 to this already exceptional groupset, means your gear changes will be quicker and more reliable than ever. Electronic Shifting For The Masses: Di2 is Shimano’s electronic gear shifting system but until now it had only been available on the Japanese component maker’s top-tier models. In introducing Di2 to the 105 range, the smooth, crisp feel of electronic gear changes are now available to a whole bunch of new cyclists. It’s no secret that Dura-Ace and, even, Ultegra are ultra-premium groupsets, only obtainable by pros and the financially well-endowed. However, no longer is electronic shifting available only to the elite. A 105 Di2 front derailleur has made electronic gear changing more affordable than ever. Over the years, Shimano have continued to review the shape and style of their electronic front derailleurs. The R7150 front mech draws on inspiration from the well-established models. It is sleek and subtle, and will easily enhance any bike it adorns. Synchronized Shifting: The 105 Di2 front derailleur is compatible with Shimano’s Synchronized Shift system. Through this system you can set up your shifting to be full synchronized, semi-synchronized, or manual. In fully synchronized mode if you shift the rear derailleur, the front derailleur can change should it no longer offer an optimum chain line. In semi-synchronized mode, the rear derailleur will automatically adjust when the front mech is changed. In manual mode, you’ll be free to choose when the derailleurs shift. What’s more, the R7150, without any cables to thread, is simple to install and easy to set up. Once you’re up and running with your 105 Di2 system, you’ll wonder how you ever managed without electronic gear changes.

The R7100 Shimano 12-speed cassette represents the first time 12-speed cassettes have been brought to the Japanese component maker’s 105 groupset; the groupset favored by recreational cyclists around the world. Better Shifting, More Performance: The previous R7000 model offered excellent shifting, even under load. The R7100 version has been refined further and boasts improved efficiency, quicker and smoother shifts. Thanks to trickle-down technology and Shimano using techniques honed in their top-of-the-range models, the products in the 105 range now perform comparably to the more expensive Dura-Ace and Ultegra lines. All that separates the ranges is the materials used, which add weight. But it’s the less expensive materials that enable the brand to the R7100 cassette at a more affordable price. Though the materials may be less expensive, this is not to say they are poor quality. Typically, Shimano will use heavier, harder wearing materials for the 105 range, when compared to the top-tier models. What you can expect is a cassette that is built to withstand and perform in the elements. How Many Teeth?: Available as 12-speed, in a ratio of 11-34T, this cassette is perfect for tackling those big days on the bike. Paired with a compact chainset up front, even the steepest of gradients should be conquerable. With an extra gear to play with, from the previous model, you won’t sacrifice a sprocket further down the block either; so you’ll have no problem keeping up in your fast bunch rides. With improved shifting when under load, you’ll also get a high-quality gear changes when changing on steep grades or if you get caught out for a sprint.

The Shimano 105 R7150 Di2 groupset is perhaps—without exaggeration—the most hotly anticipated groupset of the century. Even in mechanical form, the 105 series is widely regarded as one of the most reliable and affordable performance groupsets, with the introduction of electronic the gap between the brand’s mid-tier range and its top-tier is now closer than ever. A Battery For The Ages: The introduction of wireless shifting might leave you feeling concerned you’ll be forever charging batteries and living in perpetual fear you’ll be stranded in you biggest gear miles from anywhere. But with 105 Di2, power is supplied via two CR1632 coin cell batteries in the shifters, which should provide over three years of life. With such a range, even the heaviest of users shouldn’t find themselves in a constant state of charging and re-charging batteries. Semi-wireless Setup: 105 R7150 uses the same semi-wireless, 12-speed shifting setup as the top-tier models. The proprietary semi-wireless system means there is no longer any need from wires to the shifters to the derailleurs. Since there’s no need for wires and cables, the cockpit of a bike set up with 105 Di2 is cleaner and less cluttered than ever. Shift Into Gear: Of course with the change to electronic gearing, one of the most significant changes to the groupset is in the shifters themselves; the all-new 105 ST-R7170 levers now operate in much the same way as the top-of-the-line shifters. Shifting gear couldn’t be simpler: click a button on the shifter and almost instantly you’ll hear the derailleur whir into life. Drawing on Shimano’s years of experience in electronic shifting, you can expect smooth gear changes at the touch of a button. Without the need to accommodate levers, wires, or ports, the shape of the R7150’s levers has been brought more in line with the sleeker Ultegra and Dura-Ace shifters. The new, slimmed down, STI levers are also more ergonomically shaped, thanks to the raised hood peak and offer more opportunity to refine the reach. The Brains Of The Operation: Another significant change to previous mechanical setup is in the front and rear derailleurs. The rear derailleur is an integrated, 12-speed wireless unit, which will comfortably accommodate an 11–36T cassette. Such a wide range of gears is perfect for those big climbing days, without spinning out when the road tips back down or when you’re racing along in fast bunch rides. The rear mech uses Shimano’s Shadow technology is incorporated to reduce the risk of the derailleur hitting the chainstay in rough-riding conditions, and to provide smoother, quieter performance. The 105 Di2 front derailleur offers the smooth shifting you’d expect from the Japanese component makers. It can be programmed to be manual, or full or semi-synchronised, accommodating a 50T or 52T chainring. Crank It Up: Shimano continue to deploy their famed Hollowtech II technology in the R7100 crankset, which is now 2x12-speed. This is the same technology they have employed in the 105 range for years, and features also in the company’s premium lines. The result is a sturdy crankset, that is stiff and relatively light. Incorporated also is Hollowglide technology, which offers more precise and efficient power transfer than ever before. Shimano have been able to reduce the weight of the crankset but maintain stiffness, strength, and performance. For 105 Di2, cranksets are available as a compact (50-34 tooth) and in crank-arm lengths of 170, 172.5 and 175mm Stopping Performance: The 105 hydraulic disc brakes of the previous iteration were highly capable; for the latest ST-R7170, Shimano have further improved braking performance. The lever-action required for braking is now lighter and smoother, offering a greater area for braking control. For 105 Di2, the clearance for pads has been increased by 10%, reducing braking noise. Overall, rain or shine, you can be assured of high-performance stopping power.

The Shimano RS710 C32 disc-brake front wheel is an excellent option if you’re looking to upgrade or replace an existing one on your bike. If it’s a full wheelset you’re looking for check out the RS710 C32 wheelset This front wheel is the Japanese brand’s most affordable carbon, road wheel ever. If you’re on a budget or simply only need a replacement, then this is great option to consider. As with all of Shimano’s mid-tier products, it benefits from the experience the brand has gained from producing their premium Dura-Ace and Ultegra lines. The result is a wheel that’s relatively lightweight—especially considering the price point—yet stiff and offers some aerodynamic optimization. A Sleek Mountain Wheel A front Shimano RS710 C32 weighs a respectable 665g, making it perfect for those days spent climbing in the Alps. You might be able to find a lighter set of wheels on the market but at this price point this represents excellent value. Boasting a sleek, minimalist design this is a stylish hoop in its own right but it’s also subtle enough that you can easily pair it with an existing rear without it sticking out like a sore thumb. A Wider Rim With Better Braking The width of RS710 C32 has a wide rim profile that has been optimised for a 25mm to 32mm tyre. What’s more, the hooked-rim profile is tubeless compatible. The benefit of the extra width is that you can run lower pressure in the tyre. Although it goes against the previously accepted wisdom of using slim tyres pumped up to 120psi, a wider tyre at a lower pressure will be faster. Combine this with a tubeless setup and you’ll also experience fewer catastrophic punctures. As the RS710 C32 front wheel is engineered for hydraulic disc brakes you’ll benefit from enhanced braking power on offer from the latest disc brake technology. In using disc brakes, you’ll be confident in braking, in the wet or dry and on steep and/or long descents. So if it’s a front carbon wheel you’re in need of, that’s relatively light, reliable, and offers top performance look no further than the Shimano RS710 C32. Product Features 32mm rim depth Weight: 665g Internal-rim width of 21mm External-rim width of 28mm 24 spokes, bladed and butted Tubeless Ready Disc mount: Center-Lock 140mm disc brake rotor compatible Recommended Tyre Size: 25-622—32-622
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.
