This is simply the best seatpost available. It is incredibly light weight, and the one-piece CNC-machined post and bottom mount makes it reliable (many other light-weight seatposts have the mount physically pressed into the post). I have both the non-set back and set back versions of this post (27.2x240), and i think they're fantastic. The seat angle is easy to micro-adjust (and a clevery notched indicator helps you preserve settings), and the fore-aft saddle position is also simple.

Typically I'm not a weight-weenie, but there's no sense in having additional weight so high above the bicycle's center of gravity--you feel it in the climbs, cornering,... everywhere. The Thomson seatpost (married to a a good saddle) means I feel no weight or swing up top, and therefore more focus on the response of my bike on the road (at the wheels/fork and pedals/crank). The saddle's light weight also seems to mean a more comfortable ride for me; perhaps because there is less mass to develop harmonic vibrations or channel vibrations up through my sits-bones? I don't know for sure, but it is much more comfortable for me than my old heavy stock seatpost, especially over medium and longer distance (40+ miles). For the record, I'm 5'9" and about 160#; i ride about 5k-7k miles a year, hauling kids, light touring, and lots of club and recreation rides. I don't race, unless i'm late for work.

And here's the odd kicker--even with my old chunky Brooks Pro saddle on my Thomson seatpost the bike felt more responsive and more comfortable. The Brooks didn't work for me (after 4k miles; YMMV), and now I use a Selle Italia with even better results. It's like riding on air, it's so light and quick.

This Thomson seat post looks great and weighs 80 grams less than the stock seat post on my Specialized Epic, it's expensive but it will transfer to my next bike so I believe it's worth the price. You won't be disappointed with craftsmanship.

The subject says it all. Sturdy Aluminum seatpost that weighs less than many carbon seatposts! Who needs carbon when Aluminum is this light and strong?

You have probably read many reviews saying the same thing. As per the name, it's a masterpiece of a seat post.

The rail clamps holds your saddle in its position and angle securely using the 2 bolt design and there are markings for you to gauge the angle of your saddle when adjusting. Not going to test the strength deliberately, so no comments on that.

I have the silver one. The finishing is beautiful, it's light and does what a seat post should do very well.

5 stars. :)

Bought one in 2007 for my mtb bike (Scalpels...followed a few years later by a few Superflys...the bikes have changed the post is the same. I likely have 10,000+ mtb miles (and 4 saddles) on it and I've had zero issues - In a few days yet another frame / groupset arrives - and this post will once again remain in use..I would buy it again though at this rate I may never have to. Beautifully engineered!

Carbon seatposts are great. Until they start squeaking. Or until you do a bad re-mount at a CX race. I hate squeaks and sideways seats, so I went with Thomson. My post was cheaper than the carbon post it replaced for the same weight. I was concerned about shock-absorption and durability, but the Thomson is both comfortable and tough as nails. I can't recommend it high enough.

The seat post is light and yet robust, I am happy with that. However, I have some usability complaints:

- It has no scale for the sitting height, as my previous seat post from Specialized had. This would be a very easy thing to add and helps me to switch between my favorite sitting positions (I have three, depending on terrain).

- You need two work with two screws to manage angle and position of the seat, here the Specialized had only one screw and was much easier to handle. Also the Specialized I could adjust without removing my saddle bag, for the Thomson I have to remove it (and I don't have a bag with quick release).

So, I'll stick with the Thomson for its weight, but I'd prefer the Specialized for usability.

This is my 3rd Thomson Masterpiece Setback Seatpost. I have 3 bikes, all have a Thomson Masterpiece seatpost.

I like a little more room in the cockpit. This seatpost also sets a little more weight over the rear wheel for better traction on sketchy uphills. As a matter of fact, it is my personal opinion, I believe it improves the way my bikes handles.Thomson makes the best stuff...hands down.

This seatpost is engineered to be the benchmark that all other seatposts strive to be.

Ride more!
