Shimano GRX’s mid-priced RX600 cranks employ a 2-piece design available in a 2x10 configuration. All GRX cranksets use a new, +2.5mm chainline for increased tire and frame clearance. The 2x features a Wider-range 46-30T ratio, this, when paired with the available 11-34 cassette, offers an exceptionally low climbing gear while maintaining a ratio that allows riders to take advantage of strong tailwinds and long descents.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 Di2 electronic shifting lets you change from the big to small chainrings, or vice versa, whenever you like while minimising the risk of a dropped chain. Similarly, you can perform rear shifts without the need to trim the front derailleur to avoid chain rub. Full- and semi-synchronized shifting functions can be selected using the E-TUBE app. With digitally accurate electronic shifts and coordinated communication between shifters and derailleurs, the new Shimano 105 front derailleur offers the best shifting you've ever experienced.Great value high performance 105 double Di2 front derailleurThe Di2 front derailleur's operation is pioneering, smooth shifting is guaranteed thanks to wireless communication with the gear levers. What's more, shifting the rear derailleur automatically trims the front derailleurFull and semi synchronized shifting programable, Synchro shift compatible meaning a single shifter can control both front and rear shifting which can be fully custom tuned to your riding preferences. Semi synchronized shifting means when a front shift is made the rear mech will automatically correct to the appropriate ratioThe removal of traditional mechanical cables in favour of electrical wires that connect to the battery not only eliminates poor shifting caused by contaminates, corrosion and stretching, but provides effortless gear shiftsWireless connection to the shiftersThe front derailleur also trims automatically; the cage moves in response to the position of the rear derailleur on the cassette to ensure no chain rub and a quiet unobtrusive ride, enabling you to concentrate on the road aheadDesigned to work with the wider gear pitch spacing Shimano chainset without sacrificing shifting performance on bikes with 135 / 142 mm O.L.D.Braze-on fit as standard; if your bike does not have a braze-on mount seat tube adapters are available12-speed E-tube SD300 wire compatible
