The 400x100mm Pulse
Stepping. Better.


STEPPING IS BETTER.  IT JUST IS.  The Pulse™ stepping seatpost allows you to precisely adjust the height of the post in repeatable increments to suit the terrain or desired ergo position, or drop it fully down out of the way when needed; all by convenient handlebar control while you ride.

NO GUESSWORK. MORE CONFIDENCE. The Pulse™ stepping mechanism elimimates guesswork to find ideal saddle height. The result is intuitive confidence; focus on the trail.

ENGINEERED TO BE BETTER. SO IT IS.  The Pulse™ seatpost is the brainchild of a design team that abhors compromises and always wants it all. The fundamental design of the Pulse™ post is better than the competitors, and it has a host of important features that they lack.

REVOLUTIONARY. CONTROL.  The Pulse™ stepper seatpost will change the way you ride, by making the saddle height a precisely controllable characteristic of your bike. You can step through the increments, or you can move freely with infinite adjustment like any ordinary dropper post. It's not just 'up' or 'down'. It's everything in between, repeatably, confidently, easily.

FRAME GEOMETRY. The Pulse 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.

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

SADDLE INTERFACE. The Pulse seatpost works with standard 7mm rail saddles.

HANDLE BAR REMOTE. The Pulse seatpost trigger and ThumB lever works with most brake and shifter configurations. Please see our Remote Options and Compatibility page for more information.
