What the World Needs Now…is an XC Dropper Post.

There are a lot of positive first looks in the marketplace right now, about Thomson’s new dropper seatpost.  For example, MTBR has some great pics and video of the seatpost...and it looks like a well-thougtht-out piece of kit:

Lord knows Thomson makes lusty parts, and I’ve been very happy with the blingy Thomson parts that I’ve used in the past…seatpost on the ‘Dummy…stem on the Mukluk:

Thomson’s new dropper seatpost weighs in at 450 grams…or about exactly a pound.  That’s a little more than double the weight of a host of non-dropper, carbon seatposts out there, like the one on my Superfish.  Pretty impressive.  Given Thomson’s history, I’m hoping for a quality build, as well.  My first experience with a dropper seatpost was a Gen 1 Crank Brothers Joplin…which spent more time being repaired than it did being ridden, and which soured me on droppers.

When the Thomson gets out on the market, I’ll probably give one a shot.  I waver back and forth on adjustable seat posts…but if someone could make a lightweight, durable one, I’d be interested.  There is no doubt that there are advantages to a high saddle for pedalling efforts, and a low saddle for technical terrain.  In all reality, though, I don’t need something terribly complicated.

  • I have no need for infinite adjustment…I just need 2 positions: 1) fully extended (set up the seatpost in the frame at the standard, full leg extension optimal pedaling height); and, 2) a dropped position, with some marginal amount of drop (figure 2-3″).
  • I don’t need infinite adjustment in between fully extended and dropped.  It will either be up or down.
  • I don’t need 5″ of adjustment…I cannot imagine ever having it extended or dropped that much.
  • I really don’t even need auto-raise or lower (or handlebar controls).  I’d be happy to reach down and pull the saddle up, or reach down and release it to go down.
  • I really don’t want hydraulic, air, or other pressurized systems with seals and such.  Make it simple.  Light.  Mechanical.  Reliable.
  • Make sure that it maintains saddle alignment, and doesn’t have fore/aft or lateral play when up or down.

Sure, there are Gravity Droppers out there, and other mechanical droppers (and a host of air/hydraulic droppers).  But I think the product could be improved.  And I suspect there are other riders who would give up infinite adjustment and automatic raising if they could cut the weight penalty in half (or more), and have a product that is dead reliable.  Call it an “XC” dropper seatpost.  I can positively guarantee that you’d sell at least 1.
