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 GRX gives them the options they need to Explore Beyond, tailoring their drivetrains to suit their needs and exceed their expectations.

Rear Fix-G Track HubsAn ever present headache with traditional fixed hubs is the assembly of a drive sprocket that is attached by a thread being pulled in both directions by the pedal torque. The usual solution to avoiding the sprocket unwinding itself from the hub is a left-hand threaded lock-ring, butted up tight against the sprocket. But, as many riders have found out, this system can be quite volatile.We thought, there has to be a better way......and the solution - an HG splined hub body, with sprockets that slide on and an independent lockring that never has to handle rotational forces from the drive.Halo Fix-G advantages:Easy and secure fixing and servicing.,Adjustable chainline - 41 to 52mm.,Accepts 12 - 20T sprockets.,No need for chainwhip tools.."Halo's HG spline system is so obvious and brilliant that other brands must be kicking themselves for not thinking of it first. It can't slip or thread; it's way easier to fit or swap and will take down to 12t cogs, it's genius". Ty at the Footdown - www.thefootdown.co.uk"The Fix-g hub is great! It runs smoothly as the previous Halo hub but the fact that you can move the sprocket for a perfect chainline is great and you can feel the difference straight away. Also, it's really easy to do, everyone can do it without a mechanic's help." Ivan Fiorilla, 5th Floor riding club - London. www.the5thfloor.co.ukNote: The HG spline must ONLY be used with 7mm wide "fat foot" sprockets such as Halo Fat Foot sprockets or Gusset Double Six sprocket to avoid the cog biting into the alloy splines on the hub. Regular width HG sprockets should NEVER be used.SpecificationsMaterial Alloy forged and CNC machined,Drillings 32H, 36H or 48H depending on model,Bearings 2 x 6000 series Japanese sealed bearings.,Axle Hollow M10 Cr-Mo axle,Spoke Hole Circle Diameter (PCD) 62mm,spoke hole size (diameter) 2.5mm,Centre to Flange Left and Right: 34mm,OLD 120mm,Colour Black, Silver or White,Weight 328g.
