    A True Masterpiece

    • Familiarity: I've put it through the wringer

    Thomson is my go to post if I'm staying ridgid. I have had this post on a number or road, mountain, and cyclocross bikes. I often prefer it over "better" carbon posts. It does its job without fail.


    • Familiarity: I've put it through the wringer

    The only conceivable advantage of a carbon fiber seatpost over the Thompson Masterpiece would be flex. In a 31.6mm, you wont get much beneficial flex from carbon anyway. Save the money and get the Thompson. It is lighter than most carbon posts and it is durable too.

    The fore/aft adjustment screws makes it super easy to adjust the saddle.

    Best Rigid Seatpost

    • Familiarity: I've put it through the wringer

    Thompson makes a great product. Fact. This seatpost is awesome. It is an alloy post that is pretty light and every easy to adjust the angle of your saddle. I like the 350mm length because then I don't think I have any extra material. I love this post

    The name says it all

    • Familiarity: I've put it through the wringer

    Thomson Masterpiece is the best alloy seatpost available hands down. Made in the good ol' USA, I had a Thomson Masterpiece on my full carbon road bike because the thing is so dang light that it saved several grams over some of the more popular carbon posts. One cool thing about Thomson is that they make this post in just about every conceivable seat post diameter. The machining on this post is first-rate, and it comes with a cool canvas carry bag... because you want, nay, need one.

    Thomson Masterpiece Seatpost

      Every bike you own should have a Thomson post on it. The Masterpiece keeps all of the burliness of the classic Thomson post and shaves grams, because a lighter seatpost will make you faster right? There are lighter options but I've broken one of those mid-crit and tried to finish the race. I will say this: there are a few places where you should not aim a jagged piece of carbon fiber. After that experience, I've sworn off of the featherweight junk and onto Thomson. The fact that they've made a lightweight post is certainly a nice extra.

      light and bombproof

        Seriously, you can't beat this seatpost without paying another $200 for some boutique POS. True, it's not carbon so you don't get the look-factor but this is lighter (and much stronger and stiffer) than any of the other carbon posts I've used (FSA, Alpha Q, Specialized). There's absolutely no flex and the micro-adjust head is incredible when it comes to getting the saddle angle just perfect. Oh, and because we're always worried about weight, it came in at over 80 grams lighter than my FSA SLK-Light post
