Dropper seatposts are quickly becoming standard equipment on mountain bikes across the globe, and for good reason. Jagwire’s Pro Dropper kit helps ensure they work as well as possible. The kits included dropper-specific 0.8mm Pro Polished inner cable interfaces seamlessly with remote levers and actuator arms to provide effortless cable movement. And the innovative 3.0mm LEX-SL housing is more flexible than standard shift housing, allowing for easier installation with internally routed seatposts and providing smoother cable movement. With all needed parts included, Pro Dropper Kits are simple to install.
