It just works

Dropper posts are awesome until they're not. That's why we created the Drop Line to be the one you can rely on. From installation to activation, no other dropper post can withstand the rigors of real-world riding and just keep functioning. And since cable installation is so easy, swapping from bike-to-bike is as easy as with a non-dropper seatpost.
