Vivo Spin shifter with F T T technology.

Wrap your hands around the bars for a nice leisure ride and you will find these levers integrate beautifully into your grip. Soft-touch advance shifting with plenty of paddle area to access with your thumb. The floating thumb trigger makes release shifting effortless while still maintaining a comfortable grip on the bars. It allows the thumb to curl in its natural motion rather than being bent back at the knuckle. The release lever also has adjustable reach with the turn of a dial to accommodate different thumbs. It's easy to get to, because your thumb can move over the advance lever, keeping it closer to the bar, instead of under it like with other levers. This 9-speed shifter is adjustable inboard and outboard with its floating perch design.
