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
The introduction of Di2 to Shimano’s 105 front derailleur represents a dramatic leap forwards for the Japanese brand’s most popular groupset. Even in its mechanical form, a 105 front mech offered smooth, precise gear shifts; the addition of Di2 to this already exceptional groupset, means your gear changes will be quicker and more reliable than ever. Electronic Shifting For The Masses: Di2 is Shimano’s electronic gear shifting system but until now it had only been available on the Japanese component maker’s top-tier models. In introducing Di2 to the 105 range, the smooth, crisp feel of electronic gear changes are now available to a whole bunch of new cyclists. It’s no secret that Dura-Ace and, even, Ultegra are ultra-premium groupsets, only obtainable by pros and the financially well-endowed. However, no longer is electronic shifting available only to the elite. A 105 Di2 front derailleur has made electronic gear changing more affordable than ever. Over the years, Shimano have continued to review the shape and style of their electronic front derailleurs. The R7150 front mech draws on inspiration from the well-established models. It is sleek and subtle, and will easily enhance any bike it adorns. Synchronized Shifting: The 105 Di2 front derailleur is compatible with Shimano’s Synchronized Shift system. Through this system you can set up your shifting to be full synchronized, semi-synchronized, or manual. In fully synchronized mode if you shift the rear derailleur, the front derailleur can change should it no longer offer an optimum chain line. In semi-synchronized mode, the rear derailleur will automatically adjust when the front mech is changed. In manual mode, you’ll be free to choose when the derailleurs shift. What’s more, the R7150, without any cables to thread, is simple to install and easy to set up. Once you’re up and running with your 105 Di2 system, you’ll wonder how you ever managed without electronic gear changes.
