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. 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 C32 disc-brake wheelset, along with the deeper-section C46, is the Japanese brand’s most affordable carbon, road wheelset ever. Drawing on their experience in producing the more premium Dura-Ace and Ultegra lines, Shimano have crafted a wheelset that balances aerodynamic advantage, with weight and overall rigidity. A Wheelset for Mountains Weighing a respectable 1,511g for the set, the Shimano RS710 C32 is perfect for those big days spent cycling in the mountains. Although there might be lighter wheels on the market—though perhaps not this price point—you certainly won’t feel weighed down by these hoops. With a lighter wheel you’ll feel the zip when you put down the power, getting you up to speed in no time. Whether you need a quick burst of acceleration to crest a sharp hill or to see off a potentially race-losing attack, the RS710 C32s won’t leave you watching the peloton motor on without you. Wider Rims, Better Braking Boasting a wider rim profile than any other Shimano wheel at this level, you’ll be able to fit a wider and tubeless tyre; the benefit of this being you can run the tyre at a lower pressure. It’s widely accepted now that, contrary to past beliefs, running a wider tyre at lower pressure reduces rolling resistance, which in turn increases speed for a given power. Furthermore, a wider tyre will work more effectively with a wider rim in terms of aerodynamic performance, again offering you more speed for less effort. The Shimano RS710 C32 is engineered for hydraulic disc-brakes, meaning you’ll benefit from the stopping power offered by this braking system. The advantages of discs over rim brakes have now been widely accepted: you’ll have consistent performance in the wet, you won’t have to fear overheating your rims on long and/or steep descents, and you won’t be concerned about your expensive rims eroding away every time you break. Lastly, for the mechanically minded, Shimano have stuck with their tried-and-tested cup-and-cone bearings in the hubs. This is similar to the used on many of the brand’s hubs, which are highly regarded for their reliability and simplicity. So if it’s a carbon wheelset that’s relatively light, reliable, and offers top performance look no further than the Shimano RS710 C32. Product Features 32mm rim depth Compatible with 11- and 12-speed Weight: 1,511g for the pair Internal-rim width of 21mm External-rim width of 28mm Spoke count: 24 front and rear Hub design: cup and cone
