Instead of telling gravel riders what they needed, we asked them what they wanted. Shimano spent two years listening and countless hours speaking with gravel enthusiasts from all over the world. We took to dirt and gravel roads, narrow singletrack paths, creek crossings, and mountain passes to test ourselves and our notions of drop bar cycling. We pinned on race numbers and packed up bikepacking bags. We choked on dust and reveled in mud. And the result of all that riding and all those new friendships? First, Shimano’s Gravel Alliance and now, Shimano GRX, the world’s first dedicated gravel component series.Choice. Shimano’s new GRX line is all about choice. Shimano doesn’t want to pigeonhole the way you ride, or decide for you what the best solution is for your riding style. While we’ve long been fans of double chainring drivetrains, we also recognize the value of a single chainring system. With GRX, Shimano offers both, each with gearing options that allow you to tailor your drivetrain to suit your tastes.With two different derailleur cage lengths, Shimano GRX ensures stable shifting and chain retention across a wide range of gearing options. Looking for maximum range while maintaining road cassette progression? Go with GRX’s 800 series 2x11 RD-RX810 or Di2 RD- RX815 rear derailleurs, designed for close ratio clusters, with 48/31 chainrings and an 11-34 cassette. Paired with 700c x 40mm tires, it delivers a top gear similar to a road bike with 25mm tires and a 50 x 11 gear. And on the low end, with its 31 x 34 combination, you get a gear that early mountain bikers would envy. It is the lowest gear currently on offer for premium road drivetrains (aside from Shimano’s own GRX 2x10 30-36 offering), perfect for climbing loose, dirt and gravel surfaces.Want to drop some weight, simplify your shifting, and still maintain a versatile range? Consider the 1x11 GRX option with either Shimano’s 11-40 or 11-42 cassette and a 40 or 42-tooth equipped crankset, shifted by a RD-RX812 or Di2 RD-RX817 wide ratio rear derailleur. You’ll lose a little, absolute top speed, but still love the 1:1 low gear ratio. If you live in an area without sustained or steep climbs, you might love the smaller gear steps of that same 1x11 front chainring with an 11-34 cassette. Options abound.What about when the weather turns autumnal and you contract a case of cyclocross fever? GRX 1x11 can quickly transform from gravel fun to CX focused with the change of a cassette.No matter the option you select, GRX rear derailleur offerings feature Shimano’s SHADOW Plus chain stabilizer that can be turned on or off depending on conditions. SHADOW Plus revolutionized the mountain bike world and now it’s been tuned for gravel and rough road riding in GRX. With a quieter drivetrain, SHADOW Plus helps you engage with your surroundings and enjoy time outside.Today’s gravel riders demand more of their bikes and of themselves. Shimano GRX gives them the options they need to Explore Beyond, tailoring their drivetrains to suit their needs and exceed their expectations. We’ll see you out there!Designed for riding on rough roads, through gravel and mud, to be able to carry on in comfort, stress-free, to wherever you want, to allow you to achieve that unique sense of accomplishment.

Introducing SHIMANO GRX.Game-Changing Innovation.Even on the roads less travelled, our new GRX tech will keep things smooth, silent and safe – with you always in control.Designed from the ground up for gravel adventure.Mix and match components to customise your bike for a wide range of terrains – and ride the way you want!.Key Features:Ergonomic power curve,Integrated cable tension adjustment,Natural stroke feeling,Chainline +2.5 mm vs. conventional road FD,17T front range,More cable routing options,Lighter front shifting,Wider tire clearance,Wider range front gearing,Precise and easy front derailleur adjustment.
Specifically designed for road cycling, the Shimano Ultegra R8000 front derailleur features an updated link construction and an integrated cable tensioner for lighter front shifting operation and easier setup. Another highlight is it flawlessly moves your chain up and down, without extra effort. The result is a shift that is precise and direct, with no delay. It also matches the wider pitch of Shimano's R8000 chainset, creating increased compatibility with disc brake road frames. Technologies: HG-EV: HG-EV cassette sprocket is for rider-tuned gear combination and cadence management. Shimano provides the optimal 11-speed drivetrain gear ratio; you can choose from the wider and closer gear combinations available to match various riding disciplines. HG-EV cassette sprocket is obtained 11-speed gear without compromising the 10-speed durability and improved HYPERGLIDE shifting HG-X11 Chain Compatible: Silky driving, accurate shifting. HG-X11 directional chain ensures smoother shifts and greater overall performance. The right and left sides are optimised for front and rear shifting respectively Manufacturer's Part Number: FD-R8000-F
The clad steel / alloy / steel rotor construction of the Shimano ice tech rotor allows heat generated from braking to radiate quickly through the aluminium core achieving surface temperature drops of around 50 degrees C. When used with Ice Tech pads surface temperatures can drop from around 400 to 300 degrees C, this provides great improvements in performance all around. Freeza rotors allow the alloy core to extend out from the braking surface as fins to the centrelock mount adapter to provide added cooling. Ice Tech rotors achieve long pad life, less noise and less fade due to improved heat dispersion. The Shimano dura ace disc rotors are durable lightweight and rigid, using the proven centrelock system giving increased strength and security with an easy set-up. Plus, the precision cut and drilled braking surface improve pad clearing in muddy conditions while aiding cooling under high load. Finally, the large alloy spider is highly rigid and lightweight support for the rotor surface.
Designed for precision, this fantastic component is packed with some of the finest Shimano technologies for unbeatable performance. It features a rear stabiliser which reduces chain slap and chain drop, so you'll benefit from a lighter and more efficient gearing experience as you weave from trail to trail. Giving you more range without sacrificing any rhythm, its famous Dyna-Sys technology improves gear quality and driving efficiency, so you can get the most out of every off-road adventure. One final highlight is this version is also compatible with HG-X11 chains for smoother and more precise driving and climbing. Technologies: Shimano Shadow RD+: Less distraction quiet drive train. Rear derailleur stabilizer reduces chain slap. Simple solution for chain drop. Lighter and more efficient than roller type chain device Dyna-Sys 11: Rhythm and Range. The real advantage of 11 speed is the ability to have all the range you require without sacrificing the rhythm you need. HG-X11: Silky driving, accurate shifting.

The superb Shimano M8100 brake lever features an action-optimised design, which includes tool-less reach adjust and free stroke adjust for a rider-tuned feel. Its optimised axle position with an additional contact point and refined ergonomics give you greater braking power. Intuitive and versatile, this MTB-specific model keeps your focus on the trail, so you can ride your bike confidently. Technologies: Servo Wave Action: When you pull a Servowave 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: This brake lever is equipped with a reach adjust mechanism. The distance from the handlebar grip to lever can be adjusted to suit any hand size, type of riding and individual rider preferences. Free Stroke: The distance from the initial lever position to pad contact point can be adjusted to suit any hand size, type of riding and individual rider preferences. I-Spec EV: I-Spec EV creates a clean and action-optimised cockpit that provides greater focus and flexibility for a wider range of riders. The wider adjustment range allows riders of various styles, preferences and body styles to adjust to the optimal position. Ergonomic design, quicker lever access, and light operation enhance rider comfort and concentration.
