RockShox Reverb Dropper 1x Remote Black, One Size

Since SRAM is its sister company, it's no surprise that RockShox is helping the one-by revolution along by providing a dropper post that takes the place of your front shifter. After all, with a 50t bailout gear out back, the only left-handed adjustment you need to make between climbing and descending is getting your saddle out of the way before you drop in.
