Shimano XC9 S-Phyre (XC902) MTB ShoesCreated for the riders tackling World Cup cross country mountain bike and cyclocross races, the XC9 S-Phyre (XC902) MTB Shoes are a no-compromise off-road race shoe that you too can enjoy on local trails and at the races.Bringing together the stiffness of a premium road race shoe and blending it with the durability and ruggedness of a mountain bike shoe, the XC9 S-Phyre (XC902) MTB Shoes are those of you who love to ride hard and fast across cross country trails and during winter cross races. A Heart of CarbonWith 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, 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 latest Shimano's 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 ZonesBorrowed from the RC902 road shoe, the XC9s utilise the same functional-specific zones to enhance foot stabilisation and minimise energy loss. This sees 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 dialsWhen 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.

These industry leading HollowTech II cold forged hollow crank arms have evolved to increase rigidity, reduce weight, and improve strength. Saint HollowTech II integrated bottom bracket design uses a wide bearing placement and a large axle diameter for increased stiffness and efficiency combined with longer bearing cup threads for added durability. Saint M820 series cranksets are Dyna Sys 10-Speed compatible giving the rider more gear combinations whilst maintaining a low weight. The Shimano Saint M825 crankset's reinforced pedal and crank arm interface has a T-nut style steel threaded bushing while the crank arm profile gives excellent ankle clearance, which also increases rock clearance by removing unneeded material from the end of the crank arm. Gravity riding has progressed with bikes being lighter and trails getting faster. Saint has evolved with this providing a stiff, strong and durable HollowTech II crank set reinforced in all the ways that most extreme chainsets are not.

Although the crank arms and spider arms are noticeably bigger, which increases stiffness, the overall weight has dropped by 7g over the previous edition of Dura-Ace. Shimano has adapted the crankset to work with disc brake road bikes that generally have 135mm rear hub spacing and shorter chainstays without the need to increase Q-factor thanks to its wider chainring spacing. The Double version offered here comes in numerous gear combinations to best suit each individual riders needs. Please note: Bottom bracket is NOT included

HG-EV cassette sprocket is obtained 11-speed gear without compromising the 10-speed durability and improved Hyperglide shifting. Hollowtech II: Providing the best balance of stiffness, strength, weight and rotating performance. 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 weight, a key element of the crankset, you want light, aids in cycling longer distances over which the rider needs to pedal more. Naturally, Shimano strove for the optimum balance between the conflicting needs of stiffness while producing a lightweight crank. Hollowtech technology is an ultra-lightweight hollow crankarm created by Shimano with the company’s own proprietary forging technology that also maintains rigidity. The addition of Hollowtech II technology integrates the bottom bracket axle with the right crankarm for more stiffness and weight savings to achieve a high-dimensional balance. Its outboard bottom bracket bearing system provides better weight distribution and more pedalling stability, allowing for more efficient power transfer. The Hollowtech II crankset has been developed by pursuing the optimum balance of stiffness & rotating performance in a lightweight and beautiful crankset design. High Precision Sealing. Moreover, Hollwotech II crankset has a high-precision sealing in the bearing area to increase durability maintaining the excellent rotating performance for long periods.

RX810 series cranks offer Shimano’s widest-ever delta between small and large chainrings, a 17-tooth gap, that also debuts the company’s first ever 48-31T option. This, when paired with the available 11-34 cassette, offers an exceptionally low climbing gear while maintaining a 48-11 ratio that allows riders to take advantage of strong tailwinds and long descents. RX810 series cranks also are available in a 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. All GRX cranksets use a new, +2.5mm chainline for increased tire and frame clearance.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.
