SHIMANO 105 ST-5700 left shifter 2x(silv)

The Shimano 105 ST-5700 or ST-5703 shift/brake lever is a dual control lever with Shimano Total Integration technology, i.e. it combines braking and shifting functions. Three versions can be distinguished: ST-5700-L for controlling the front derailleur with 2 chainrings (left mounting), ST-5703-L for controlling the front derailleur with 3 chainrings (left mounting) and ST-5700-R for shifting the rear derailleur with 10-speed cassettes (right mounting). The brake lever joint has been repositioned for easier operation from above. The adjustable reach via spacers also contributes to ergonomics and comfort. With the 105 STIs, you will thus be able to better dose the braking power in all situations, especially since the Super SLR technology optimises the response.
