Shifty is small enough to squeeze between your brake lever and grip. It has 2 primary buttons for shifting and a 3rd button that can be used for dropper or front shifter toggle. Precisely machined from 6061 Aluminum. Split clamp design means you don’t need to remove the grip to install. The super flexible flat cable plugs into the BlakBullet hub for full wireless shifting or dropper control. If your bar has internal routing, put the BlakBullet inside the bar and run the Shifty cable internal for a totally stealth installation.
