SHIMANO 105 Di2 R7170 2x12V Groupset

The SHIMANO 105 Di2 R7170 2x12V groupset revolutionises gear shifting for road cyclists, guaranteeing smooth and effortless performance. Thanks to Di2 technology, every gear change is instant and precise, even in the most demanding conditions. The compact and ergonomic gear lever enables optimal control in all circumstances, offering increased comfort and perfect mastery, whatever the riding position.

The system offers a considerable advantage by preserving the cyclist's energy, allowing them to focus on the enjoyment of the ride and the effort required without worrying about drivetrain failures. Gear shifting happens automatically via a switch, eliminating the lever travel required for mechanical systems. This feature is particularly useful for adjusting gears according to variable road conditions.

Shimano D-FLY bridges the gap between component technologies and Di2 software. D-Fly enables connectivity between Di2 systems and compatible ANT+/Bluetooth®LE accessories such as cycling computers/GPS units and lights. It also offers a wireless connection with the Shimano E-TUBE PROJECT Cyclist app for smartphones, enabling you to customise gear lever configuration, search for firmware updates and troubleshoot component faults.

The sub-1:1 ratio of the SHIMANO 105 12-speed drivetrain allows you to tackle more ambitious climbs while keeping better control of your effort. The synchronised front derailleur ensures consistent pedalling and smooth gear changes, while the E-TUBE PROJECT app allows personalised adjustment. The new SHIMANO 105 braking system, inspired by the professionals, makes high-performance braking accessible to all cyclists.
