Over 40% stronger on ultimate strength test than the strongest production seatposts on the market.
Over double the fatigue life of any other production models we tested. The tube and head of the Thomson seatpost are integral-machined from one single piece of high strength 7000 series aluminum. The head is not pressed or bonded in. This allows for superior strength and minimum weight, allowing higher strength at low weights.
Lightweight - approximately 188 grams (250 length) for road bikes and 228 grams (330 length) for mountain bikes. Natural ellipse bore inside tube for optimum strength to weight ratio.
We have a long 1.614 inch (41 mm) seat rail grip length. This helps prevent seat rail bending from impact loads. Most brand-x seatposts have grip lengths of .500 inch or more shorter than our grip length.
The Thomson seatpost design incorporates a bending fuse to prevent catostrophic failure. All brand-x seatposts we tested - every one of them - failed in catastrophic failure with the seat and clamp components - and sometimes pieces of the tube and head - flying off in all directions. This type of failure would dump the rider.
The Thomson seatpost has a clamp, head, and upper tube strong enough to withstand 350 foot-lbs of torque. The tube will start to yield and bend at the seat tube clamp at about 250 foot-lbs of torque. Remember all brand-x posts we tested flew apart at less than 150 foot-lbs of torque. Under severe impact the Thomson seatpost would bend slightly and allows the rider to come to a safe stop or finish the ride. The ride could continue.
Thomson Elite Layback Seatpost Features:
Every component of the Thomson seatpost is 100 percent American made. This includes all fasteners and forgings.
The Thomson seatpost has all parts captive and can easily be attached to a seat without disassembly.
Infinite tilt adjustment minus 5° and plus 29°.
Very low profile clamps - no seat interference - swivel nuts are down between the seat rails.
The designs and materials have passed extensive life and ultimate strength tests.
Every production lot of seatposts will have ultimate strength and fatigue tests performed. Our on going testing program insures that every production lot of seatposts meets Thomson standards.
Impact absorbing clamps - clamps, head, and assembly will spread and flex on impact to protect seat, rails, seatpost and rider.
Adjustments can be made to the tilt of the seat without moving the seat forwards or backwards.
Easy on seats - allows seat to survive heavy impact loads without bending rails

I can't believe the difference this has made to my ride. The ability to move my seat back just that the little bit further has improved my knee position and made riding a lot more comfortable.

Bought this item to replace the giant seatpost that I had on my Giant Anthem X3 and I am definitely satisfied with it. Very solid seatpost which also allows you to adjust your saddle very easily to fit your riding style.

Top notch seatpost, quoted as being a much better option then carbon at this price range. Good for oval carbon rails too. Very easy to adjust with the two bolt system.
I bought the 31.6mm 367mm layback, weighs 222g.

Rated 5 out of 5 by Anonymous Beautiful piece of engineering
I've had mine for just over a year. I'm six foot plus and around 14 stone. Never creaked once. Its finish is beautiful. You may think it hard to get excited about a seat post but all things Thomson are things of beauty. I've got the X4 stem and the seat post, collar as well and they are shiny lovely things. I call them my precious.. In all seriousness. Get one. You won't be disappointed. Also, I recently found out Thomson are soon to release a carbon handle bar! Good times... Start saving those pennys..

Rated 4 out of 5 by Anonymous Beautiful and well made but there is a but!
As far as seat posts go there is no doubting this is an exquisite piece of engineering, it is all one piece and it is light and stong too and I am very happy with it, it looks stunning on my steel Genesis....however.....be WARNED >>>>> if buying the layback post, as per other reviews, I can confirm that if you have your seatpost high and saddle tilting forward towards your stem then you wont be able to with this post as the bracket has been engineered level with the layback and not tilted forward so most of the adjustment angles available point your saddle tip skywards, mine is set on the most extreme of available angles forward and my saddle is just level. Come on Thompson you can do better.....otherwise awsome product.

Beautiful post, top quality workmanship. I bought a 27.2 400mm Ragley from CRC but it was always slipping slightly and was a bit heavy. This post stays put, doesn't creak, is light and strong and looks absolutely sublime. I love my bike even more now.

Rated 3 out of 5 by Anonymous Bent it
I don't give a s*** about the colour or finish, I just want them to stay straight. I am a skinny tall runt but seem excellent at bending seatposts (yes, I read the manufacturers instructions about mounting the damn things). The thompson layback post, although coming prebent, has lasted me the longest (about a year) before getting another bend in it. But I must say I am a little disappointed after being assured by all and sundry that I "wouldn't bend a thompson". So, it is possible to bend a thompson while riding cross country without being too extreme.

Rated 3 out of 5 by Anonymous Quality but not the angle of dangle!
Fantastic quality as always, but and it's a big but, the layback post only just about manages to get your saddle to level, being tall I have about 280 mm of post showing and normally have my saddle tilted low at the nose pointing to headset this is the perfect attack angle for me - but is not possible with this post!! The fixing mech has been engineered the easy way with the mech inline with the layback part of seat post which automatically means its set pointing to the sky and can only just about manage to get level at its max - rather than the mech being engineered at 90 degrees to the vertical section so you'd then get a full range of adjustment. Will take it for a ride in morning and see if I can live with it!
