The Genius 10 Road Mega Cycling Shoes deliver the performance you need to hit your training numbers and push for race wins. With a stiff carbon composite sole unit, you'll be powering out of corners with immediate response during a criterium race and chasing KOMs up the toughest of mountain passes. Durable Upper The upper is moulded from a tough and durable material, designed to take on the rigours of daily training and weekend racing. However, it's also supple enough for immediate comfort out of the box. A water-repellent finish lets you ride comfortably when weather conditions take a turn for the worse and it's eco-friendly too. A stiff reinforced heel cup then keeps your foot firmly in place as you apply pressure to the pedals. No matter how hard you're pedalling or for how long you're in the saddle foot stability is optimised. Tecno 3 Dial Getting the right fit is also essential to road riding performance and here you'll find the Soft Instep Closure 4 system and Techno 3 dials create the perfect combination to get it just right. The Instep Closure 4 system features a wide, EVA thermo-formed padded strap which spreads pressure evenly over the instep for optimal comfort levels. Adjustment is then available with the Tecno 3 dials. The upper keeps the fit secure while the lower dial allows for precise adjustment across the toe box for the perfect fit every time you ride. No fuss. Just twist and go. Carbon Composite 20 Sole Balancing stiffness for pedalling efficiency and dialled flex for long-ride comfort, the Carbon Composite 20 Sole is ideal for the aspiring racer and speedy sportive and Gran Fondo rider. Nylon is injected with carbon fibre to ensure rigidity while weight is kept to a minimum. The carbon fibres also ensure there's no degradation to the stiffness rating over time - these high-performance road shoes are built to last. That long-term durability is also evident in the replaceable heel pad- once it's worn out it's simple to replace, thus prolonging your shoe's lifespan. Cleat Guidance These Road Shoes are compatible with road bike pedal systems that use cleats with 3-bolt standards, such as: Look Delta and Keo, Shimano SPD-SL, Speedplay Light Action, Zero, X-Series (via 3-hole adapter plate), Campagnolo Pro-Fit, Mavic Zxellium, Time Iclic/Xpresso and Time Impact.
If you love nothing more than chasing the thrills of riding off-road at high speeds - be that leg-burning XC mountain bike races, the lung-busting efforts of cyclocross or the cut and thrust of gravel events, the Vento Ferox Carbon MTB Shoes deliver the instant power transfer and comfort you need to perform at your best. Tear up the Trails When you're pushing the pace you don't want unnecessary bulk or weight to slow you down. And the Vento Ferox definitely won't hold you back. The upper is an innovative design using materials engineered to deliver a snug, supple and lightweight fit but one that's also incredibly durable. Excellent tear-resistance maintains off-road durability while excellent breathability keeps feet fresher during the heat of competition. BOA® Li2 Fit System x Fizik Powerstrap To give a precise and comfortable fit, the Vento Ferox combines the precise fit of a BOA® Li2 Dial with the secure, foot-hugging comfort of Fizik's Powerstrap design. The Li2 dial features a composite over-mould to give improved grip and input toque, making it easier than ever to tighten and loosen your shoes. With quick and easy micro-adjustment, fine-tuning the fit to your particular foot shape is now incredibly easy. With a lower profile than previous versions, the Li2 dial also marginally improves aerodynamics while also making it less vulnerable to being accidentally hit - ideal for rough trails and close competition. Meanwhile, the Powerstrap system features a wide, lightweight and reliable hook and loop strap system that, unlike a traditional strap, pulls together the two sides of the upper thanks to the ribbon wrapping around the foot. This provides even pressure across the whole foot and delivers an unrivalled level of riding comfort with minimal bulk and less complexity. Carbon Outsole Achieving a 10 out of 10 on Fizik's stiffness scale, the UD carbon composite sole unit will ensure you surge ahead of the pack with maximum efficiency and ruthless accelerations. With your power going straight to the pedals all your hard training to get race fit isn't wasted. When you're off the bike, all-terrain traction is taken care of via the rubberized tread across the heel and to the outside of the cleat area. And for particularly muddy races, you can add toe studs to boost grip - perfect for the steep muddy runs of cyclocross in winter. 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.

Instead of telling gravel riders what they needed, we asked them what they wanted. Shimano spent two years listening and countless hours speaking with gravel enthusiasts from all over the world. We took to dirt and gravel roads, narrow singletrack paths, creek crossings, and mountain passes to test ourselves and our notions of drop bar cycling. We pinned on race numbers and packed up bikepacking bags. We choked on dust and reveled in mud. And the result of all that riding and all those new friendships? First, Shimano’s Gravel Alliance and now, Shimano GRX, the world’s first dedicated gravel component series.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. We’ll see you out there!Designed for riding on rough roads, through gravel and mud, to be able to carry on in comfort, stress-free, to wherever you want, to allow you to achieve that unique sense of accomplishment.
