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

DT Swiss s benchmark setting AERO+ rim matched to a punchy mix of top end Aerolite and Aero Comp spokes, laced to premium Ratchet System hubs makes for a wheel that delivers in all riding situations.47mm deep carbon clincher tubeless ready rimSpokes: DT Aerolite and DT Aerocomp straight pull spokesHub type: 240 with SiNC ceramic bearingsOptimised for 25-28c tyresWeight: 706g (front), 832g (rear)Maximum recommended system weight: 120kgThe ERC 1400's rims were designed from scratch in conjunction with former F1 head of engineering JP Ballard and his team at the GST wind tunnel in Immenstaad, Germany. Using a bespoke fluid dynamic analysis system that for the first time allowed the designers to model and quantify the effect of crosswinds on a wheel's handling a rim profile was developed that gives an optimal balance between aerodynamics and handling. This is why the ERC 1400 rim is precisely 47 mm deep and 27 mm wide, any wider and you'd see an unacceptable increase in drag, any deeper and you'd compromise handling in rough conditions, we call this concept Aero+ and the result is a blindingly fast yet truly all conditions wheel.DT's renowned 240 hub internals are combined with a freshly optimised SPLINE hub-shell designed to improve spoke bracing and improve stiffness, an upgraded 36-tooth ratchet ensures lightning fast engagement. A carefully chosen blend of Aerolite and Aerocomp straight pull spokes offer a great blend of strength, speed and comfort. For those looking to use the latest tyre tech the ERC 1400's come tubeless ready but can also be used with standard clinchers. The front wheel comes ready for 12 x 100 mm thru axles, the rear comes ready for 12 x 142 mm thru axles. Includes tubeless rim tape and valves.
