Masterpiece Setback Seatpost

If you love the sleek lines of the Thomson Elite Seatpost but are looking for a little more setback in your position, the Masterpiece Setback Seatpost is just the ticket. The Masterpiece has taken the clean lines of the Elite a step further by machining all of the surfaces of the aluminum post. This saves enough weight to put the post in at 158 grams, with all of the durability and beauty you've come to expect from Thomson. The head features tilt adjustment from minus 5 degrees to plus 29 degrees. The swivel nuts have been placed beneath the clamps to give it a low profile.

Perfect Post

I've put it through the wringer

I have put 1000+ miles on this post, and never had an issue. Adjustments to seat angle are super easy, post looks great and provides a good amount of setback for taller / leggy riders. 10/10 would recommend.

Rad Post

I've put it through the wringer

This post is the bomb. Super light weight and has the brand behind it. You can't beat a Thomson Masterpiece post if you're trying to make your bike a one of a kind. People will become jealous and point it out.

Chasing grams, I had a famous maker carbon post on this rig and broke the rules attaching a seatpack for bikepacking. Short story—carbon post failed—I heard it crack and then examined it and broke it off by hand. Enter, the tried and trusted Thomson. Not the lightest, certainly not the heaviest. You know what they say—Strong, Light weight, Low Price; pick two… This is strong and pretty light. I’ve got Thomson posts on some of my other bikes (road and mountain)—forgot how great they are—probably because they just work. Easy adjustment for the seat to dial it in perfect. Then set it and forget it…holds the rails of the seat like a vise. No worries about shards of carbon piercing the nether regions with a Thomson post.

looked great, however I didn't try it because it didn't fit. Sent it back.


Is this compatible with a Bontrager saddle with 7x10 carbon rails?
