Enjoy quicker, more precise front shifting and efficient power transfer thanks to its HOLLOWGLIDE structure. It cuts weights yet maintains stiffness, strength and performance. What’s more, the crank arm length starts at 160mm so smaller riders can benefit from SHIMANO’s legendary shifting.An attractive aluminum crank with hollow arms for lightweight, rigidity, and durabilityThe newly designed crank arms offer an optimized balance between lightweight and efficiency. The crank, formed with hollow aluminum technology, is anodized with a beautiful gloss black anodized finish, giving it a luxurious look. The resin ribs on the back of the chainrings are SHIMANO 105's unique structural design that achieves both thorough weight reduction and crisp shifting performance.Key Features:Optimal balance of stiffness, strength, weight and rotational performance,HOLLOWGLIDE structure cuts weight yet maintains strength for better power transfer and quicker, more precise front shifting,Crank arm length: 160, 165, 170, 172.5, 175 mm Gear combination: 50-34T, 52-36T Q-factor: 148 mm.
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.
