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.

When it comes down to performance and durability the new Rival 22 rear derailleur matches the top end Force and Red derailleurs with the only difference being a slight weight difference. The derailleur is constructed from an aluminium inner and outer cage as well as an aluminium b-knuckle. Using Exact Actuation, each gear shift is fast and accurate, with the redesigned AeroGlide jockey wheels keeping things quiet and smooth.
Newly redesigned the Shimano M7000 SLX 11-Speed Shadow+ Rear Derailleur takes cutting edge technology from the XTR and XT groupsets and brings it down to a more affordable price range. Brings Cutting Edge Technology from XTR and XT Level to an Affordable Price PointShadow+ Clutch Mechanism for Excellent Chain RetentionShadow Design Optimised For 40-46t SprocketsDirect Cable Routing Prevents Snagging on Trail Size HazardsSealed Bearing PulleysThe lightweight and low profile design combined with the direct cable routing prevents those unwanted snagging moments on undergrowth or something a little harder, helping to keep your shiny rear derailleur in one piece and still attached to the bike. Drivetrain security goes even further with the Shadow+ Clutch design. As we push our bikes harder dropping a chain is the last thing you need. With Shadow+ dropped chains should be a thing of the past. The M7000 SLX rear derailleur is optimised around 40-46t cassette sprockets, being compatible with a maximum of a 42t cassette when used with a double chainset, or with a 46t if used with a single chainring. Sealed bearing pulleys ensure this derailleur is designed to go the distance. Tough, light weight and great value, SLX M7000 is a great choice for those seeking top performance without having to re-mortgage!
SRAM’s Apex 1 drivetrain gives the gear range and the shifting simplicity to let you simply go where you want.

By eliminating unwanted chain movement, X-Horizon shifts faster, puts an end to ghost shifting and reduces shift force and chain slap. And with Cage Lock technology, wheel removal and installation are easier than ever. Cage Lock With Cage Lock technology in the rear derailleur, wheel removal and installation, as well as chain installation, becomes faster and simpler. Just pushing the cage forward to create slack and lock it into place. Roller Bearing Clutch Features Roller Bearing Clutch (RBC) rear derailleurs deliver maximum drivetrain stability—even through the most punishing terrain. With RBC technology, derailleur bounce and chain slap are eliminated without sacrificing precision. X-Actuation Developed specifically for SRAM 1X, X-Actuation keeps shifting sharp and consistent across the entire 10 to 42-tooth cassette. X-Horizon The X-Horizon rear derailleur’s ‘straight parallelogram’ design limits all movement to the horizontal axis, which makes ghost shifting impossible while also reducing shift force. For quicker, more exact shifting, the large upper pulley offset design maintains a constant chain gap across all gears. X-Sync SRAM X-Sync 1X chain rings provide the highest level of performance and durability. The SRAM X-Sync tall square teeth edges engage the chain earlier than traditional triangle shaped teeth. The sharp and narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-Sync chain rings have been designed with mud-clearing recesses for the inner chain links and rollers. Engineered in Germany, X-Sync rings are an integral part of the SRAM 1X drivetrain.
The X-Actuation technology eliminates slop whilst the Roller Bearing Clutch technology delivers maximum stability making the SRAM GX 10 speed rear derailleur great over punishing terrain. This technology also removes shifting variation and offers you incredible shifting speed and precision. Cage Length Information: Short Cage option has a total chain wrap capacity of 30T (Ideal for use with downhill (DH) / enduro bikes with a smaller chainring up front) Medium Cage option has a total chain wrap capacity of 35T (Ideal for use with all mountain (AM) / trail bikes with a medium chainring up front) Long Cage option has a total chain wrap capacity of 47T (ideal for use with touring bikes with a larger chainring up front)
