The ergonomically designed dual control Shimano 105 5700 Shifters Double designed for use with a double chainset. The shift cables are routed under the bar tape and re-development and positioning of the internal mechanism provides a faster, lighter and smoother shift. The ergonomic shift arc follows natural hand movement with inward shift stroke distance reduced for rapid and precise gear changes. The brake lever pivots have been positioned to increase power and improve ergonomics when riding on the hoods. Tuneable reach adjusters enable custom fitment for all hands. These shifters come complete with silicon greased cables to further reduce shift friction and increase service life.
