SHIMANO 105 is a mid-range road group that inherits competition technologies and design to offer a truly unique balance of performance, reliability, and value. Shimano 105 brings new energy to road cycling with its completely renewed interface and 12-speed mechanical shifting. 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 fit a wide range of hand sizes and reduce the distance between the bar end and the lever. The lever is more efficient, providing greater control with less effort.

A transmission for different cyclists
Here is the low gear ratio you've always wanted. The SHIMANO 105 12v sub 1:1 gear range allows you to tackle the steepest climbs and better control your physical effort along the route.

Slowing down has never been so enjoyable
Thanks to the new piston design, racing brake standards are now available to an even greater number of cyclists. The new SHIMANO 105 braking system lets you advance in your cycling journey, experience the joys of efficient braking, and push beyond your limits.
