The power multiplication factor then increases rapidly at the pad-to-rim contact so more of the lever stroke is used to apply greater braking power with improved control. Reach Adjust: Brake lever is equipped with a reach adjust mechanism. The distance from handlebar grip to lever can be adjusted to suit any hand size, type of riding and individual rider preferences.A 2-year warranty is offered with all Shimano products from Chain Reaction Cycles (3 years on Dura-Ace and XTR products).Buy Shimano Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
Key Features:The 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 derailleur,Full 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 ratio,The removal of traditional mechanical cables in favour of electrical wires not only eliminates poor shifting caused by contaminates, corrosion and stretching, but provides effortless gear shifts,The 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 ahead,Designed to work with the wider gear pitch spacing Shimano chainsets 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 available,12-speed E-tube SD300 wire compatible.
To integrate the use of dropper posts in gravel, SHIMANO created the GRX mechanical ST-RX810-LA left hydraulic disc brake lever that, when used with a 1x11 drivetrain, can control a dropper post while also keeping the cockpit tidy. The use of an integrated cable pulling system allows for 9mm lever throw to operate a dropper post.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.

As seen on the feet of the World's best XC mountain bike and cyclocross racers, the XC9 S-Phyre (XC902) MTB Shoes make no compromises in their pursuit of pure race-ready performance. They blend the stiffness of a performance road shoe with the rugged toughness of a mountain bike shoe. It's one for the racers out there. A Heart of Carbon With their super-stiff carbon sole, the XC9 shoes deliver rapid acceleration straight off the start line. And once you're on the go, the incredible power transfer lets you maintain speed as you tackle sharp uphills, accelerate hard out of berms and drop your rivals as you speed across technical trail features. Meanwhile, if you're off the bike and running or pushing, the ULTREAD™ sole comes into its own. Lightweight but durable and grippy, this keeps you sure-footed on loose ground, mud and over rocks. Extended rear lugs give extra confidence on downhill slopes while the wide-spaced tread also prevents mud from clogging up the shoe and disrupting easy pedal entry. Shimano Dynalast The improved Shimano Dynalast design improves the fit and feel of the XC9s but maintains the superb support and stability it's renowned for. A 360-degree surround upper hugs the foot, offering a stable pedalling platform for efficient power transfer throughout your pedal stroke. It also sees an optimized toe-spring section that ensures efficient and powerful pedalling with a reduction in foot fatigue over long distances. The toe box shape has also benefited from further refinement and the improved design now offers comfort to a wider range of foot shapes. To the heel, an anti-twist heel cup and glass-fibre reinforced heel stabiliser work seamlessly together to resist flex and instability during your higher power output efforts. Function Specific Zones Borrowed from the RC902 road shoe, the XC9s utilise the same functional-specific zones to enhance foot stabilisation and minimise energy loss. This sees both non-stretch and flexible materials deployed in key zones, giving you the very best in foot stability, perfect venting, minimal weight and the aforementioned minimised energy loss when pedalling. Dual BOA® Li2 dials When it comes to a precise fit, the twin BOA® Li2 dials give you the ultimate in quick and easy control. Micro-adjustment for both tightening and loosening ensure you get the fit just as you want it every time you ride. And as feet swell in the heat or you want to tighten up for a sprint, you can make quick adjustments on the fly. The Li2 dials also benefit from an improved construction to aid durability while also being lower profile to enhance aerodynamics. Cleat Guidance These MTB shoes are compatible with MTB pedal systems, which use cleats with SPD standard (2-bolt standard), e.g.: Shimano SPD, Time ATAC, CrankBrothers, CrankBrothers Race, Look MTB, Xtreme MTB, Wellgo MTB, Ritchey MTB.
