Shimano Dura Ace R9150 Di2 Groupset

Shimano Dura Ace R9150 Di2 11 Speed Groupset
What every serious Shimano aficionado has been waiting fro
The DURA-ACE Di2 groupset is the result of Shimano’s ongoing passion for technology. This is reflected in every single component in the groupset. All components are joined together to work as one, reinforcing each other for unparalleled performance.
For the new DURA-ACE Di2 groupset, Shimano have improved upon each and every individual component. Together they form a truly superior groupset. A perfectly balanced total system. Improving performance by maximising efficiency: that’s how Shimano are able to ensure the best for cyclists with the highest demands.
In addition to traditional “Full” Synchro Shift, riders can optionally select “Semi” Synchro Shift. This intuitive new mode automatically reacts when the rider shifts from one chainring to another, automatically shifting the rear derailleur to minimise the gear step, thus preserving the rider’s rhythm.
Di2’s E-Tube system provides unmatched shift performance, reliability and rider customisation. Along with enhanced Di2 functionality, expanded E-Tube wire options and junction boxes as well as the new EW-WU111 Wireless Unit, deliver improved wiring configurations and wireless connectivity to Shimano’s E-Tube Project.  
The 9150 Di2 components can be connected to Shimano´s E-TUBE software, which supports the programmable aspects of the Di2 electronic gear shifting system. Additionally, via Bluetooth technology, this is also accessible on smart phones and tablets.

Great Customer Service

Great Customer service. They allowed me to specify exactly which chainset and cassette combination I wanted as well as choose between regular and direct mount brakes, and a choice of two bottom bracket styles. I asked them to send out what they had while waiting for the brakes, which weren't in stock, which enabled my local bike shop could start the fit. This they did and furthermore they sent the brake out when it arrived as next day delivery for me without charge. Only one fly in the ointment (which was just a lack of understanding on my part) is that neither of the Shimano bottom bracket choices offered was any good for my Trek emonda SLR - as it uses its own specific type. Nonetheless, the groupset offered great value for money, especially with the flexibility to choose exactly what you want.

Super service

I got my order nice and easy

Dura Ace Di2 groupset

Delivery within a week and great communication throughout. Groupset fitted without any problems. It does not look like you get a lot for your money but a lot of the stuff is hidden away inside my frame. British weather meant I put it through extreme testing on Saturday and it never missed a change and never mis-shifted once. Best purchase ever and worth every penny. Credit to Vanilla Bikes because they do not charge you more for the 11-30 cassette, unlike other websites. I also opted for the 34-50 chainset at the front and it works very well. Note You will need to update firmware to get the semi-synchronised and synchronised shifting to work via junction box A. It took me some time to realise this. You just download the e-tube project from shimano, plug the charger lead into the junction box A and the other end into the USB port of your computer. The e tube program allowed customisation of the three modes of shifting and also allowed switching modes through junction box A. It did seem to deplete the battery and I thought something had screwed up but I just recharged the battery and all was good. I believe you can update firmware via Bluetooth but will need an extra wireless device to allow this to happen. I would not bother unless you want to hook up to a Garmin. The e-tube project has two versions and you need to download the newer version to allow it to recognise the 9100 groupset. Make sure you have at least Windows 7 installed. Anything older will only allow the old e-tube project to be downloaded and this does not recognise 9100 groupset.


Delivery very slow. Not taken out of box yet. So cant rate groupset so only rated on delivery.
