Shimano GRX’s mid-priced RX600 cranks employ a 2-piece design and are available in 2x11 and 1x11 configurations. 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.RX600 series cranks also are available in a 40T single chainring option for those who prefer the simplicity and decreased weight of a 1x11 drivetrain with one of Shimano’s wide ratio 11-40 or 11-42T cassettes.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 105 chainsets are known the world over for their reliability and performance. Having been refined from the previous version the 105 R7100 furthers this reputation. For this edition, Shimano have carefully engineered the R7100 crankset to offer an excellent balance between stiffness, strength, weight, as well as rotational performance. The result is a chainset equally suited to big days riding in the mountains, as it is fast bunch rides. Trickledown Performance Thanks to the benefit of trickle-down technology, the difference in quality between a 105 chainset and the more premium Dura-Ace or Ultegra versions is closer than ever. Now, with the addition of Di2 to the 105 R7150, the decision to purchase anything more expensive is even less justifiable. That is, of course, unless you simply want to spend the money on the flashiest tech around! All The Tech As with any product from the Japanese component giants, the FC-R7100 chainset employs some of the company’s top tech. Shimano’s famed Hollowglide technology means the outer chainring is hollow, to reduce weight but is engineered to do so without diminishing strength. This is the same technology employed on a number of the brand’s cranksets, including the top-tier models: Dura-Ace and Ultegra. Additionally, Hollowtech II technology is used to keep weight to a minimum, while maintaining strength and stiffness. The result is a crankset that won’t leave you bogged down on a climb and ensures maximum power transfer from your legs to forward motion. Again, this is the same technology employed in Shimano’s top-of-the-range models. Whether it’s the perfect chainset for big days out on the saddle or something for racing your local criterium the 105 R7100 is the perfect option, particularly for those slooking at a more affordable price range. It offers smooth shifting, an excellent balance between weight and stiffness, and won’t break the bank. Product Features: The Hollowglide structure reduces weight but maintains strength Crank Arm Lengths: 160, 165, 170, 172.5 and 175mm Gear Combination: 50-34T Q-factor: 148mm Weight: 765.6g (50T, 172.5)
