The new Racing 5 DB wheels are the perfect choice for endurance bikes. The lower aerodynamic resistance and decreased stiffness, achieved with the lower 24 mm U-shaped profile, makes them the ideal technical choice for long rides without having to worry about climbing, rain or wind, with a consequent saving in energy and increased comfort. In this case to the aluminium rim has seen an increase in the inner channel width, up to 20 mm from the previous model’s 17 mm, and the addition of the innovative 2 Way Fit system, to comfortably fit 25-28 mm tyres, both clinchers and tubeless (tubeless tape installed and valves included). The aesthetics have undergone the same intervention as the Racing 4 DB model, with the new laser etched graphics, ensuring the long life of their striking design.
The Shimano 105 Di2 RD-R7150 rear derailleur is quite possibly the biggest advancement in 105 technology since the range was introduced. In its mechanical form, 105 offered excellent shifting performance; the introduction of electronic gear changing offers even quicker and smoother shifting than ever. With a 105 Di2 rear derailleur at your disposal, you’ll have access to lightning-quick, effortless gear changes at the click of a button. What Big Teeth You Have: The 105 R7150 rear derailleur comes with a greater range of gear capacity. Coming as 12-speed and capable of handling a 36T cassette, it’s the perfect rear mech for tackling those big days out on the bike. Pair it with a compact chainset up front and there’ll be very few mountains you won’t be able to tackle. Such a broad range of gears will have you confidently tackling steep climbs, taking on bikepacking adventures, or getting stuck into fast bunch rides. From The Shadow: Similarly to Shimano’s top-tier lines—Dura-Ace and Ultegra—and drawing on the company’s mountain bike ranges, the 105 Di2 rear derailleur uses the “shadow” design. This design is intended to increase stability when shifting on rough roads and under load. With such technology you can be confident when changing gears on those steep inclines and when caught out in a race. What’s more, the shape created from this design is sleek and compact, reducing the risk of damage in the event of crash and increasing your aerodynamic advantage. Wireless Indicators: Though the 105 Di2 rear derailleur is compact in its design, it’s still chocked full of technological wizardry. It includes an integrated wireless unit that, in conjunction with the shifters, offers seamless gear changes free of cables. Handily, the derailleur features LED status indicators to let you know: battery status, when the unit is paired, and when it is in adjustment mode. Product Features: 12-speed Di2, electronic gear changes LED Status Indicator, to signal battery status, pairing, adjust mode Weight: 302g Max low gear: 36T Max high gear: 11T
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.

All set for racing, this brilliant component features a durable alloy body construction which allows it to withstand all the rowdiness that comes with adrenaline-fuelled competitions. Shimano has gone a step further with this model by equipping it with a carbon fibre reinforced polymer lever for phenomenal actuation strength without any excess weight weighing down your handlebars. Adjustable Di2 Road Shifter Engineered for accuracy, this stunning version is kitted out with a tooled reach adjust mechanism. This allows you to easily tweak the distance between your handlebars and the lever to suit your riding style, hand-size or the terrain conditions. As a result, you'll benefit from a more skilful grip as you pull the lever as well as more precise shifting performance due to it feeling like a natural extension of your limb. Technologies: SEIS: A technological innovation of the computerized shifting system based on the DI2 concept with which is called, the SEIS (SHIMANO ELECTRONIC INTELLIGENT SYSTEM). The SEIS innovative shift technology is still based on the SHIMANO INDEX SYSTEM (SIS) that has proved its superior gear changing characteristics over the years. The big difference is that in this case, the shifting action is provided for by electronics instead of mechanics. This electronic shifting system has been extensively tested over past two years by several professional riders in all conditions possible, such as rain, mud, low temperatures, cobble stone roads and combinations of all of these at the same time. Shifting is executed by simply pressing the button. No power is needed to shift, which gives important advantages since it is easier now to always keep a tight grip on the handlebar and to keep your concentration on riding instead on shifting. The shift system allows accurate and effortless shifting in difficult circumstances for example when you have cold hands or when you are completely exhausted. Furthermore, the shifting performance will never be affected by contaminated or stretched cables since the shifting signal is transferred electronically. The operating buttons work similarly to mechanical DUAL CONTROL LEVER so you don’t need to re-program your mind for the SEIS. 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. E-Tube: The E-TUBE platform's “Plug & play” and D-FLY wireless connections make it easier than ever to check the system's status, and apply customized settings to DI2 and SHIMANO STEPS components with a PC, tablet or smart phone. Wirelessly customize functions like SHIMANO SYNCHRONIZED SHIFT over Bluetooth® while out on a ride. Automatically checks for firmware updates on each startup to ensure all components are running the latest version. PC, smartphone and tablet applications can help you quickly diagnose errors and simplify the repair process. Beautiful visualisation of your real-time SHIMANO STEPS riding data on your smartphone. Advanced all-weather design resists rusting, stretching, and freezing.
