Thomson Masterpiece Seatpost

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)
190g (27.2mm, 330mm)

Great 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.

PROS: Cred Points On The Trail, Strong Construction, Attractive Design, Lightweight

CONS: Saddle Attachment, Price

Does not slip, does...
Does not slip, does not break, easy to adjust. If the post is going to be installed on a bike with a shot peened finish, make sure that all ofthe mini bb's have been cleaned out before installing the post, if not, you will scratch the post.

Best Seatpost on the Market
The Thomson Masterpiece post is a beautiful piece of machining that works flawlessly, is very easy to adjust and very lightweight. While probably overkill for most people's needs (Who REALLY needs a seatpost this nice), it appeals to the connoisseur who only wants the best.

It's lighter than many carbon seatposts out there and the finish lasts a very long time through many abrasions through a seat tube.

As a bonus, it's designed and machined by real, live Americans in the aerospace industry in Macon, Georgia. It's an investment... some people will think it's worth it, others won't.

PROS: Lightweight, Strong Construction, Attractive Design, Great Mounting System

BEST USES: Road Biking, BMX, Mountain Biking

The Thomson Masterpiece takes their Elite post to the next level. It's lighter than most if not all carbon seatpost, very strong and Made in the USA.

PROS: Strong, Lightweight, Made in the USA

Will always use thomson seatpost they are the best. My bike came with a carbon fiber offset post and I tried that out fo ra day and took it right out. I perosnaly do not like the flex the a carbon seatpost has. Overall Thomson is great!

Worth every cent!
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)

PROS: Beauty, Weight

the only seat post manufacturer i trust
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.

PROS: Quality control light

CONS: none

I love them!
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.

PROS: Light and stiff

CONS: Dirt builds up under seat
