FREE TorqueKey™ with every Fall Line R.  The Fall Line R seatpost comes with a FREE TorqueKey, so that you can set-up your seatpost exactly right. And you can use this handy tool for your other components, like stems, too!

MECHANICAL DropLoc™ TECHNOLOGY.  The Fall Line R dropper seatpost allows you to infinitely adjust the height of the post in a new way.  A mechanical brake locks the post in position without having to circulate large amounts of hydraulic fluid.  It's lighter, more reliable, and has faster return speeds.  The mechanical lock is SPRING actuated, so even if air pressure is lost, the post still locks in any position (but of course the post will not return without help).  Now that is reliability!


SMOOTH RETURN  The Fall Line R has a beautiful air damping system that ensures a fast, smooth return without excessive speeds. 


BOTTOM STEALTH ENTRY  The Fall Line R uses the highly coveted bottom 'stealth' entry for bikes that have internal routing options.  Unlike other posts, the Fall Line R has a NO TOOLS easy disconnect. This means you can easily install and remove the post anytime without having to cut the cable! The cable connection has an ANTI-PULL design which means adjusting the height of the post will not effect cable tension.

FRAME GEOMETRY. The Fall Line R seatpost works well with most mountain bike geometries. Some frames with extreme seat tube angles and rearward saddle position may pose problems. Some frames with curved or interrupted seat tubes may experience post depth insertion issues. Please check the drawing to ensure that it will work with your cockpit.


INTERNAL 'STEALTH' CABLE ROUTING. The Fall Line R uses an internal cable routing configuration that attaches to the bottom of the post.  Most new bikes are ready to accept the internally routed cables.  Some customers choose to make a cable entry location on the seat tube of their existing bike. 


SEAT TUBE DIAMETER. The Fall Line R seatpost works well on any mountain bike that uses a seatpost that is either 30.9mm diameter, or 31.6mm diameter.  


SADDLE INTERFACE. The Fall Line R seatpost works with ALL typical saddles, including  7mm  round-rail saddles, 8-10mm oval-rail saddles, metal rails and carbon rails.
