Elite road racers demand reliable and precise shifting, 12-speed Dura-Ace R9150 delivers with its super-lightweight and compact design Synchronized Shift designed, developed to choose the next biggest or lowest gear ratio irrespective of whether a gear change needs to be made by the front or rear derailleur The Di2 front derailleur's operation is pioneering, smooth shifting is guaranteed thanks to wireless communication with the gear levers. What's more, shifting the rear derailleur automatically trims the front derailleur The biggest difference you will notice is just how much quicker and effortlessly smoother shifting on the front chainrings is, even under load The removal of traditional mechanical cables in favour of electrical wires not only eliminates poor shifting caused by contaminates, corrosion and stretching, but provides effortless gear shifts The front derailleur also trims automatically; the cage moves in response to the position of the rear derailleur on the cassette to ensure no chain rub and a quiet unobtrusive ride, enabling you to concentrate on the road ahead Braze-on fit as standard; if your bike does not have a braze-on mount seat tube adapters are available 12-speed E-tube SD300 wire compatible

The consistent stopping power provided by Shimano’s latest 105 BR-R7170 hydraulic disc-brake calliper makes bike riding that much more enjoyable; regardless of whether you’re descending mountain tops in the wet or racing your friends in the dry, you’ll get the stopping power you’d expect. The 105 hydraulic disc calliper represents the most cost effective way to experience the excellent stopping power offered by Shimano’s performance-oriented disc-brake systems. Although slightly heavier than Shimano’s top-tier models, it offers similar levels of performance to them. So, if you want premium-level performance, at a more reasonable price point, these callipers are certainly worth consideration. Better Braking All The Time: It’s no secret that more and more bike makers are prioritising disc-brake bikes and that an ever increasing number of riders are experiencing the performance benefits of disc brakes. It’s no surprise why, the benefits of disc brakes are numerous: consistent stopping power in the wet or dry; no risk of over-heating and damaging expensive carbon rims on long descents; better brake modulation; and it enables manufactures to make wider wheels, that accommodate larger tyres. Braking Excellence: In the updated BR-R7170 calliper, Shimano have improved the heat dissipation and overall braking control. Whether you’re descending an alpine mountain in the blistering sun or making a sudden stop in the rain, you can rest assured your brakes will work all the same. Further improvements have been made by the Japanese component makers. Pad clearance has been increase by 10%, which will reduce the noise that can occur with disc brakes. Attention has also been paid to the maintenance and bleeding process, which have been improved to make home maintenance a simpler process. A convenient one-way bleeding system, combined with an easy hose joint system, makes for simple installation and adjustment.
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.
