Featuring a smaller lever size and new positioning, the Ultegra R8025's lever improves the overall braking and shifting experience for riders with smaller hands. With a redesigned internal shifting unit, you'll benefit from its quick and intuitive gear changes and operation. Enjoy greater control in all conditions with some of the best technologies at your fingertips helping you wherever the road takes you. Behind the "click" you hear and feel every time you shift, is its Shimano Index Shifting System technology providing you with light, precise and consistent gear changes. Completing this set is a powerful flat mount caliper which gives you constant stable braking without any power loss. Its oversized pistons use Ice Tech technology to achieve an optimised low weight, high rigidity and excellent heat dissipation. Furthermore, this technology transfers hydraulic power directly to the brake pad and ceramic material is used to avoid heat transfer. As a result, you'll benefit from longer lasting stopping performance and modulation, making it an ideal upgrade for going further than before ride after ride.

BMX HollowTech II crankset for serious racing using the new external bottom bracket bearing system to maximum effect Lightweight yet rigid design is highly durable and incredibly strong HollowTech II bottom brackets bearings are mounted outboard of the frame increasing there diameter and placing them more widely apart; this dramatically changes the load on the bearings increasing rigidity and bearing service life We recommend that this bottom bracket is initially installed by a bike shop to ensure perfect bottom bracket facing and fit Comes complete with chain ring fixing bolts and nuts For use with a single chainring in a choice of sizes from 34 tooth to 46 tooth
The XTR M9100 12 Speed Cassette has been created with an increased transmission ratio, is 30% stiffer than previous models and keeps a lower weight to maximise efficiency when making those vital shifts. Equipped with a 10-45 or 10-51 teeth system, cadence jumps when moving between gears are kept low to maintain high-speeds and steady rhythm as you blast through your run. Featuring Hyperglide+ technology, the cassette benefits from small shifting ramps leading the chain to the next sprocket when going up through the gears and on the way back down, stopping the chain from dismounting. This ensures consistent gear-stepping at all times with no impact to your cadence. A fantastic set of sprockets for the thrill-seeking trail and downhill rider, the XTR M9100 12 Speed Cassette is more than equipped for the rowdiest of rides.
All set for adventurous rides, this stunning component features a sturdy aluminium construction which makes it more than capable of handling the challenges of an all-day epic. Delivered as the crankset only, it is equipped with a 1x and 2x compatible direct mount transmission which allows you to choose a chainring size that best suits your riding style separately. This is the ultimate choice of upgrade for riders who want more freedom to customise your crank setup for achieving a podium-topping finish. Please Note: This product page is for the Crankset only, chainring sold separately. Technologies: Providing the best balance of stiffness, strength, weight and rotating performance The concept of HOLLOWTECH II technology is focused on producing a superior crankset which will maximize a rider’s power transfer. The rigidity of the crankset ensures pedaling efficiency while its weight, a key element of the crankset, you want light, 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. HOLLOWTECH technology is an ultra-lightweight hollow crankarm created by SHIMANO with the company’s own proprietary forging technology that also maintains rigidity. The addition of HOLLOWTECH II technology integrates the bottom bracket axle with the right crankarm for more stiffness and a weight savings to achieve a high-dimensional balance. Its outboard bottom bracket bearing system provides better weight distribution and more pedaling stability, allowing for more efficient power transfer. The HOLLOWTECH II crankset has been developed by pursuing the optimum balance of stiffness & rotating performance in a lightweight and beautiful crankset design. High Precision Sealing Moreover, HOLLOWTECH II crankset has a high-precision sealing in the bearing area to increase durability maintaining the excellent rotating performance for long periods.
Designed for the highest speed environments and modern tyre widths, the Ultegra C60 wheelset shares its all-carbon rim profile with Dura-Ace but employs a hub that is compatible with both 11 and 12-speed cassettes. For situations where aerodynamics is the priority, the new Ultegra R8170 C60 wheelset features an all-carbon, 21 mm internal, tubeless compatible rim and a super-fast cup and cone bearing hub that is compatible with both 11 and 12-speed cassettes. Centre-Lock Disc Rotor Mount The Centre Lock system makes an easy rotor installation possible with a spline mount and a lock ring. The lock ring mounting system reduces the total working hours by shortening the amount of time of both installation and de-installation. In addition, the secure fixing by the spline mount enhances precision and rigidity while improving braking efficiency. D2 Aerodynamic Rim Profile Aerodynamic performance is affected by wind direction. To create the D2 rim, Shimano engineers considered both frontal and crosswinds, aiming to achieve optimal performance in real-world riding conditions. Extensive prototype testing, in the wind tunnel and on the road, proved that a wide rim shape with a deep tire bed performs best across a wide range of conditions. At yaw angles ranging from 0 to 15 degrees, the Shimano D2 rim profile reduces air drag better than others aero shape rims. This rim design also boosts lateral wheel stiffness and offers improved vertical compliance for increased control, comfort and durability on the road. Rear Wheel OPTBAL Spoke System The OPTBAL rear wheel spoke system features 21 spokes—14 on the drive side and 7 on the non-drive side. Cassette spacing in today’s wheels produces unbalanced tension in traditional 1:1 spoke systems. This unbalance is intensified with the 11-speed cassette, producing nearly double the tension on the drive side spokes. Generally, high and low tension spokes have respectively tendency toward breaking down and coming loose spoke nipples. Unbalanced tension affects durability and strength. The OPTBAL design rebalances spoke tension, enhancing wheel rigidity and strength for a more durable wheel.
Now simplified with a single derailleur cage length, the new 12-Speed Shimano Ultegra R8150 rear derailleur packs the fastest, most precise shifting on the market into a more affordable option. With the fastest, most accurate shifting on the market, the new 12-Speed Ultegra R8150 rear derailleur is more versatile than ever thanks to a single cage length option compatible with 11-28, 11-30, and 11-34 cassettes. 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. Creating and continually improving the world's best shifting is a complicated undertaking requiring constant technological advancements. From hardware to software, Shimano Di2 technology is on the cutting edge, striving to deliver the best rider experience possible now and in the future. Shimano E-Tube Compatible E-Tube is Shimano's “service” that uses websites or apps to maximize the enjoyment of riding a bicycle by connecting the riders, the bicycles and Shimano. Shimano's genuine application E-Tube Project for Mobile allows you to customize your bike, update firmware, and maintain it by connecting it wirelessly to your bike. You can also get more detailed bike maintenance by connecting to your bike by wire with E-Tube Project via the Windows V4 application. Direct Mount Compatible Rear wheels are easier to remove with a mounting option for SHIMANO SHADOW RD and SHIMANO SHADOW RD+. The direct mount feature is designed to suit a wide range of contemporary frames with large-section chainstays, in particular, mountain bikes with thru-axle dropouts. Shimano Shadow Low-Profile Rear Derailleur The mechanism rear derailleur, Shimano Shadow RD, is intended for more aggressive riding. Its super low profile design carries many benefits. Because of its low profile and single tension construction, the derailleur does not hit the chain stay in rough riding conditions. The result is smooth and silent performance.
