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

A low-profile design reduces damage from contact and falls.105 Shadow design with Di2 technology, shifting is easy and precise - just a light touch, as soft as a mouse click, is sufficient for the front or rear derailleur to instantaneously select the correct gearThe rear derailleur is now the brains of the system with wireless connectivity to the shifters. It acts as the point the system is charged, provides ANT+ connection to 3rd party devises and replaces the handlebar junctionButton on the derailleur for Di2 operations, and LED light denotes synchronized shift mode, setting mode and charge requirementsSleek appearance with Low profile Shadow design construction reduces risk of damage in a crashProgrammed automatic motion at the touch of a switch makes this derailleur quick, smooth and effortless to shiftThe removal of traditional mechanical cables in favour of electrical wires to the battery not only eliminates poor shifting caused by contaminates, corrosion and stretching, but provides effortless gear shiftsDerailleur contains a saver (fuse) function, where the inner structure is protected from strong impactsHigh tolerance cold forged aluminium link plates and body construction is extremely light and durableFour self-lubricating micro-machined fluorine-coated link pivot bushings provide low-friction shifting12-speed E-tube Di2 compatibleWide gear ratio compatible up to 11-36T
Shimano GRX 600 2x11 Speed Gravel Disc BrakeThis stunning disc brake provides you with the stopping power and precision needed to tackle all the challenges of gravel riding. Its off-road inspired lever and bracket ergonomics deliver superior mixed terrain control, so you can easily ride across rough roads even in muddy conditions. Shimano has also raised the benchmark for maintaining a strong grip and modulation in any conditions by making the lever from anti-slip construction. Adjustable Gravel Disc BrakeFeaturing some of the best Shimano technologies available, you'll be able to conquer your next adventure, wherever the road takes you. Its reach adjust technology allows you to precisely customise its feel to suit your hand size, riding style and individual rider preferences. Topping it off is its Servo Wave Action technology which delivers fast braking efficiency between your pads and rotor, so you can enjoy more rapid braking power and control. Features: Use: Gravel, Road Speed: 2x11 speed Oil: Mineral oil Reach Adjust: Tooled Clamp Band Inner Diameter: 23.8 - 24.2mm Type: Dual control lever Technologies:Reach Adjust: Its 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. Ice Technologies: The fade, which can occur to disc brake rotor and pad when braking on a long downhill ride has a negative impact on the braking performance. Shimano has adopted Ice Technologies disc brake rotor and Ice Technologies pad to realise the cooling technology for consistent performance. The clad disc brake rotor blade, which has a 3 layer-sandwich structure of stainless steel, aluminium and stainless steel, provides better radiation performance achieving from 400˚C to 300˚C surface temperature. Also, the radiation fin has been adopted for the pad. Moreover, the clad disc brake rotor blade and the radiator fin provide long pad life, less noise, less fade and lightweight. One Way Bleeding: One Way Bleeding was developed for quick and easy prevention of air in our hydraulic system. We have streamlined the oil route throughout the system to prevent air bubbles from being captured in the system. One way oil routing plus a funnel tool with mineral oil provides an easy and clean bleeding system.Click HERE to check out the Shimano Brake Reference Guides.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.
