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.

Engineered for smooth shift transitions, this optimised model skips the spider to save up to 45g while giving you more range to work with. The individual tooth profile has moved from the traditional symmetrical shape to more directional specific profile with the intention to create a positive chain roller engagement to aid with chain retention, critical in preventing chain slip and bounce over rowdy terrain. When combined with taller teeth the Easton narrow/wide ring can be used without a chain guide or clutch derailleur. All Easton rings feature the Cinch Direct Mount System which means making a swap between ring sizes or even between double ring configurations a quick and easy procedure. Using the Cinch DM System also provides significant weight savings by eliminating the material overlap and extra bolt hardware which is required for a traditional spider with chainring configuration.
Perfectly suited to the increasingly popular all-mountain segment, the mrp amg v2 model shares the freshly updated "TR" upper guide with the 1x unit, and adds MRP's patented integrated skid. This All-Mountain Guide (AMG) is a great choice for 120-150mm (5-6") travel bikes when used with the latest tensioned rear derailleurs or on its own for shorter-travel trail bikes or hardtails that require bash protection. The contact-free, "upper-only" chain retention on the MRP AMG V2 alloy chain guide means it's virtually silent and completely drag-free when pedalling. The patented integrated skid will protect your crank and chainring and prevent the chain from ever contacting and potentially damaging your expensive frame. Please note: The 32-38t ISCG option comes as a plain black chain guide without MRP logos. Image is for demonstration purposes only.
The Shimano Deore M6000 10 speed double chainset benefits from the technology of Shimano's top-end models, yet it still offers outstanding value for money. Smooth and durable power transfer is provided by the two piece "Hollowtech II” bottom bracket system and quick and crisp shifting action is ensured thanks to the “Dyna-Sys” chainrings. Even under load, you’ll be able to shift with ease and maintain momentum as you beat your riding buddies or rivals to the bottom of the trail. Additional Item Top Features: - Optimised gear combinations and ratios for trail riding. - Designed for an external bottom bracket system that is lightweight and incredibly strong. - Lightweight and rigid steel bottom bracket axle. - Smooth-shifting rhythm maintains speed and acceleration over challenging terrain. - Close step tooth profile for smooth shifting. - Stable shifting performance in any suspension position. - Single spike structure for stable shifting. - Dyna-Sys compatible. - Bottom bracket not included. Technologies: Hollowtech II: The concept of Hollowtech II technology is focused on producing a superior crankset, which will maximise a rider’s power transfer. The rigidity of the crankset ensures pedalling efficiency while its low weight, a key element of the crankset, aids in cycling longer distances. Naturally, Shimano strove for the optimum balance between the conflicting needs of stiffness while producing a lightweight crank. For most frames, Hollowtech II with its 24mm axle can set the bearing position outside of the frame to provide better weight distribution and more stability. Hollowtech II bottom brackets also have high-precision seals to increase durability, maintaining excellent rotating performance for long periods.
Designed specifically for gravel riding, this superb model gives you a wider gear range for long tours and unpredictable terrain conditions. Its optimum gearing makes it immensely versatile for tackling any adventure and the challenges that come with exploring new roads. This is a perfect upgrade for riders who want increased rigidity and powerful acceleration wherever they roam. Technologies: 2-Piece Crankset: Integrated crank arm and bottom bracket. Increased rigidity with less weight. Wider bearing positioning. Rigidity is enhanced and pedalling force is efficiently transmitted. Precision Bearings. Low maintenance and simplified installation.
This item is designed to provide convenient bicycle protection in moderate to high crime areas. The hardened triple heat-treated boron manganese steel chains include 10mm six-sided links to help protect against cutting attacks by damaging cutting tools. The integrated chains are secured with a new patent-pending integrated Kryptonite Evolution Series 4 lock head. This innovative series of chains also feature a patent-pending pin-less design which secures the chain to a hardened deadbolt and allows for no weak leak in the chain due to the extensive holding power of the link itself against attacks. The chain is enclosed in a nylon-webbing sleeve to protect your bike frame's paint from scratches and allow for easy portability and tight coiling during storage. Each Kryptonite Evolution Series 4 1090 chain comes with three stainless steel keys including a lighted LED key with a replaceable battery and two ergonomic 'I' keys. These make opening a disc-style cylinder much smoother.
