Product Description

The Thomson Masterpiece Seatpost is not for everyone. We at Thomson wanted to create the best seatpost possible without regard to cost. The serious cyclist will want to own the Thomson Masterpiece Seatpost

Masterpiece posts weigh approx 40 grams less than the same size Elite model post This weight reduction was accomplished while maintaining the strength and durability expected from a Thomson Seatpost

Thomson accomplished this weight reduction by machining the seatpost all over--- including the oval inner diameter. We were able to hold closer tolerances by machining than by extrusion alone. Machining all over on an already beautiful design makes the Masterpiece Seatpost a work of art.

  • 26.8 x 240-147 grams
  • 27.2 x 240-157 grams
  • 28.0 x 240-142 grams

    All three are available straight or setback and all three can be silver or black.

    Strengths:    Light
    Striking in silver
    Permanent settings
    Saddle angle dial is convenient
    Machined from a single 7005 aluminum billet


    Weaknesses:    None...not even price!

    Bottom Line:   
    At 155g this thing is still 10x stronger than full, fragile-by-comparison carbon posts will EVER be.

    I had a machinist friend examine it and he was in complete AWE telling me the post must cost $200-$300 dollars. He was shocked how much I paid for it. The stick is a complete work-of-art. Yes, its highly over-engineered...but so is the OTHER PART LH Thomson and Co. makes- the landing gear struts for the Boeing 747 Jumbo Jet.

    If 500+ air passengers can trust Thomson- so can your precious booty!

    Strengths:    Excellent clamping mechanism for saddle, easily adjusted

    Weaknesses:    Aluminum walls too thin in places, exterior wall grooves were too large (causing stress risers), weaker than the Elite, not worth the risk for riders over 210 lbs.

    Bottom Line:   
    Thomson seatposts DO break sometimes - don't let their marketing drivel stating that the post won't "catastrophically fail" influence your purchasing decision. Installed the seat-post at start of 2007 season using torque wrench (60 in-lbs) and rode for two seasons with no problems. About two miles into a ride recently, the post snapped in half where it enters the seat-tube. Sent me down instantly - nasty crash. Had a failure analysis done on the post and the findings were that the aluminum walls had been machined too much in some places (i.e., too thin) and the machining grooves on the outside of the post were likely out of spec, causing multiple stress risers. Thomson replaced the post but did not reimburse me for repairs to the bike, nor did they write a formal reply to my inquiry letter. I've actually gone back to Easton EC90 Zero carbon post - never had issues with it. Post is probably fine for lightweight riders, but there is a limit for how thin aluminum walls can be and still provide durability.

    Strengths:    - Super strong seat post
    - Simple seat adjustments
    - Set and forget


    Weaknesses:    None

    Bottom Line:   
    What else is there to say about Thomson other than they make rock solid products! Ingenious yet simple seat clamp design allows for minor (or major) adjustments by turning 2 screws. Once the seat is mounted and torqued, it's a set and forget type of seatpost. Never have to worry about it moving and works great with my Scott CR1. I took a pipe cutter to mine (31.6) and cut off about 2.5" and it weighs a scant 180 grams!

    Strengths:    There are few absolutes in life, the timeless quality of any Thomson product is one of them.

    Weaknesses:    Perfection comes with a price and the Masterpiece is not cheap. However, look at the weights and prices of the other posts out there. The price and weight of the Masterpiece beats most of the high end carbon posts on the market. If the cost is still too much go with the Elite it is just as good, just a little heavier.

    Bottom Line:   
    I have used Thomson Elite posts on my mountain bikes for some time now and went with the Masterpiece on my road bike for the light weight, and as much as I hate to admit it "Bling" value as well. All Thomson products are a work of art that function flawlessly forever. The mounting can take a little patience but once it is set up it will never move or fail you.

    Strengths:    Strong, beautifully crafted, very light, MADE IN THE USA!

    Weaknesses:    Somewhat difficult ot adjust. Pricey.

    Bottom Line:   
    With price as no object, I began researching seatposts for my Cannondale SystemSix build project.

    I examined all reviews and products on this site, and various vendor sites. I decided upon the Thompson Masterpiece due to the fact that it is light, strong, and it is made in the USA. Actually, this CNC machined product is a work of art.

    I could not have made a better decision. I am a big guy 6'1" 225, and this post holds my Fizik Aliante solidy in place without a hitch.

    My seatpost on my C'dale MTB is always popping and losing it's position; Therefore, I have decided to replace it with a Thompson Elite seatpost.

    I recommend this product to anyone who will settle for nothing less than the best.
