You are probably already familiar with the legendary Thomson Elite seatpost. Now theyve improved it with the new Masterpiece model, which weighs in at more than 40 grams less, while maintaining the strength and durability you would expect from Thomson.

Please note: Thomson does not recommend the use of shims on their seatposts.

  • Inner machined oval saves weight
  • Tube and head machined from 7000-series aluminum
  • Head is 1-piece (not bonded or pressed) for superior strength
  • 41mm of seat rail grip length, helps prevent seat rail bending
  • Every component is 100% American made, including all fasteners and forgings
  • Infinite tilt adjustment, minus 5° and plus 29°
  • Every production lot is fatigue and strength tested
Weight: 160g (27.2mm, 240mm)

        Comments about Thomson Masterpiece Seatpost:

        Love these seatposts, have them in various sizes on three different bikes (including one road bike). Very strong and light, and I love the ridges on the post that keep it from sliding in the seat tube.

        It is expensive, though. Getting your saddle attached is pretty finicky, but I've gotten good at it with a little practice. Adjusting the saddle angle can be somewhat time consuming but it's very accurate and stays put once you set it.

          I love this seat post. Got it for my road bike and it looks dead sexy and very light weight. Will probably get another one for my mountain bike as well.

          Comments about Thomson Masterpiece Seatpost:

          I've owned several of these seat posts over the years and they are amazing. The only thing that I can thing of as a negative is installing a new saddle. It's not difficult, just annoying when trying to make finetuned adjustments.

              Comments about Thomson Masterpiece Seatpost:

              I have them on all my bikes. Road, track, Mtn. and commuter. Stiff, light, and strong. Don't have to worry about it snapping off like carbon! For mtn bikes you may have to clean dirt buildup out from under the seat from time to time.

              Comments about Thomson Masterpiece Seatpost:

              Thomson has unparalleled manufacturing and quality control.

              The Masterpiece is their most refined, light weight post. Do note, with their attention to QC and safety, Thomson gives a ride weight limit for this post.

              I've had a serious injury from another manufacturer's seat post failure and Thomson is now the only product i trust with my life. I'm 190lbs suited up to hit the bike park and feel secure using the Masterpiece for this hardcore application. It also rivals any seat post on the market in regards to weight. I'd use it on my weight wennie road bike. There might be posts out their that are slightly lighter but are you really going to count a handful of grams vs safety.

                  Use it on my Ibis since 2010, it´s perfect and a beautiful piece. A also recomend the x4 stem to make the pair. And you can use it on your repair stand without any fear (instead of the carbon´s)
