9point8’s Pulse seatpost is a new entry into the market of on-the-fly adjustable seatposts. Selling direct to consumer, mechanically actuated, manufactured in North America, black and with a 100mm stroke; its key differentiator is that it has a lever that looks like a mini brake lever – and – steps up and down in 5mm increments.
Development of the post began in earnest in 2010 with production versions available for sale in late June 2013. At a USD $ 499 price, expectations are high. Such a premium price presumes a premium product. A test Pulse seatpost was installed on a Turner Czar. With 5 rides on it so far on to the review….
Lee Lau’s Biases
I’m 160 lbs, 5’11″ and have had over 15 years experience riding bikes in North Vancouver, Squamish, Whistler, the Chilcotins and many other areas in B.C. and Alberta. I’ve also made many bike trips to Switzerland, Tyrol, Utah, Washington, Oregon, California and the Yukon (for example) so I’ve had some experience biking in a variety of terrain. My bias is towards pedalling up and unlike many people who learned to ride bikes on North Shore trails, I actually enjoy riding (and sometimes bushwhacking) uphill.
Down about 10mm to start a 1200m descent.
I have used the RockShox Reverb, KS Lev, i900 and Supernatural, Gravity Dropper Turbo, Crank Brothers Joplin and Kronolog and Xfusion Hilo dropper seatposts. I have no commercial association with 9point8.
A brief word on the company seems opportune since they are new. 9point8’s founders are Jack Pittens and Steven Park. Both are mechanical engineers with a passion for trail riding and business partners in an engineering firm since 1998. Their background is manufacturing and nuclear industries but like all good enginerds they have dreamed of mixing business with pleasure have dreamed and wondered about thow to developing better products for mountain biking. 9point8’s employees, who have contributed substantially to the seatpost design, have a similar vision.

Local riding is mainly Ontario xc on the Niagara Escarpment trails which feature up and down elevations without big sustained climbs but with lots of technical, rocky, rooty terrain. This was the birthplace of the concept for the stepping seatpost.
Presently, 7 people are involved with the company working on the Pulse post and other projects. Three are full-timers while four are part-timers.
