Shimano Group 105 7120 Disc Mech.12V

SHIMANO 105 is a mid-range road groupset that inherits race-ready technologies and design to deliver a truly unique balance of performance, reliability and affordability. Shimano 105 brings new energy to road cycling with its completely revamped interface and 12-speed mechanical gearbox. The ergonomic Dual-Control levers fit a wide range of hand sizes, while the sub-1:1 ratio offers excellent options for all climbs.

Optimized grip and comfort
The new ergonomic Dual-Control levers adapt to a wide range of hand sizes and reduce the distance between the handguard and the lever. The lever is more efficient and you get more control with less effort.

A drivetrain for different cyclists
Here's the basso report you've always wanted. The 1:1 12-speed sub ratio range of the SHIMANO 105 allows you to tackle the steepest slopes and better control your physical exertion along the way.

Slowing down has never been so enjoyable
Thanks to the new piston design, race braking standards are now available to even more riders. The new SHIMANO 105 braking system allows you to move forward on your cycling route, get to know the joys of efficient braking and push yourself beyond your limits.
