Ready to take on any road cycling challenge, this model is packed with some of the finest Shimano technologies available to bring you an unrivalled riding experience. Precisely customise its feel thanks to its reach adjust technology which allows you to adjust it to suit your hand size, riding style and individual rider preferences. Furthermore, its Servo Wave Action technology delivers fast braking efficiency between your pads and rotor, so you can enjoy more rapid braking power and control. Taking its lightweight and sleek design up a notch, Shimano has also installed an anti-slip lever which gives you superior grip and control in any weather conditions. Smooth and reliable, this is a perfect example for taking your rough road cycling further than ever before across mixed terrain conditions. Technologies: Servo Wave Action: 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. Reach Adjust: Its brake lever is equipped with a reach adjust mechanism. The distance from handlebar grip to lever can be adjusted to suit any hand size, type of riding and individual rider preferences.
Shimano's Ultegra FC-R8100 crank maintains the same quick, precise front shifting and efficient power transfer that Shimano riders have grown accustomed to, but with even more crank arm length options. Spanning 160 to 175 mm in length, Ultegra cranks now cater to smaller riders, triathletes, and cyclists curious about shorter crank arms. An integral part of Shimano's new 12-Speed road lineup, the FC-R8100 crank builds upon Shimano's legendary front shifting and transmission efficiency. With new refinements for seamless 12-Speed shifting, the Ultegra crank is now offered in lengths from 160 to 175 mm, bringing performance and improved fit for smaller riders, triathletes, and riders with specific biomechanical requirements. Hollowglide Chainring Technology Hollow technology on the outer chainring. The Hollowglide construction ensures high rigidity while its hollow structure cuts down on weight yet maintains strength. This provides better power transfer and quicker and more precise front shifting performance. Hollowtech II Forged Crank Arms A lightweight crankset not only reduces the bike’s weight but decreases rotating mass to aid in acceleration. The challenge is to reduce the weight of the crank without reducing its strength and rigidity. Shimano's advanced forging technology has solved the problem through the HOLLOWTECH crank. Just like high-quality frame tubing, a hollow crank arm can provide amazing strength and rigidity at very lightweight. Optimised Balance of Stiffness, Strength and Weight The concept of Hollowtech II technology is focused on producing a superior crankset that will maximize a rider’s power transfer. The rigidity of the crankset ensures pedalling efficiency while its low weight, a key element of the crankset, aids in cycling longer distances over which the rider needs to pedal more. Naturally, Shimano strove for the optimum balance between the conflicting needs of stiffness while producing a lightweight crank. The addition of Hollowtech II technology integrates the bottom bracket axle with the right crankarm for more stiffness and weight savings to achieve a high-dimensional balance. Its outboard bottom bracket bearing system provides better weight distribution and more pedalling stability, allowing for more efficient power transfer.
Among the greatest performing Dual Control Levers on the market, Ultegra R8150 Di2 offers 12-speed shifting with refined ergonomics and is exceptionally lightweight.

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. SLR-EV Caliper Compatible SLR-EV is Shimano's SLR braking technology with a dual symmetric pivot brake caliper. The short-arm brake design employs two bearings and a roller to realize greater efficiency in the pivot area and deliver superior modulation and power for braking. Together with the BC-9000 brake cable, the latest calipers deliver 36% more braking power than Shimano's previous brake model.
Despite its smaller, lighter design, the Dura-Ace FD-R9250 brings the fastest front shifting on the market. The fastest just got faster thanks to the Dura-Ace FD-R9250. Tipping the scales under 100 grams, the new design shifts 45% quicker than Shimano's FD-R9150, already the fastest on the market. And the frontal area of the FD-R9250 is also reduced to decrease aerodynamic drag. Shimano Di2 Electronic Drivetrain Performance Thanks to its lightning-fast, accurate, and reliable shifting performance, Di2 puts riders in complete control and ensures a seamless interface between the cyclist and bike like never before.

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
