MECHANICAL PERFECTION: Shimano 105 12-speed STI Dual Control ST-R7120 + BR-R7170 Disc Brake

The mechanical 105 is a tribute to mechanical shifting - the purest form of road cycling. It's all about the mechanics, not the software. It's about appreciation for craftsmanship and ingenuity. And also about merging with your two-wheeler on the road. Leaving all the tech stuff behind. Instead, you shift gears purely mechanically and in tune with your pedal stroke. In short, pure shifting pleasure for your self-powered adventures.

The first and only mechanical 12-speed group from SHIMANO is the newest member of the premium product line. The mechanical 105 combines pure cycling with the purest craftsmanship. Inspired by the 105 Di2, it too offers a wide gear range and the low gradation you've always wanted. Based on SHIMANO's Science of Speed philosophy, the mechanical 105 offers high performance at an attractive price. This is especially interesting for riders who want to climb every mountain - and on the road like to travel at high speed.

With proven hydraulic braking technology, the new SHIMANO 105 2-piston calipers BR-R7170 feature the SHIMANO Flat Mount System and its low-profile design that is ideal for road bikes. More compact and lighter than ever, the R7170 brakes offer wide pad clearance for easy wheel removal and quiet performance as well as one-way bleeding for easy, clean maintenance.
