Q & A


Special Limited Edition Union Jack Anodised Thomson Elite Seatpost. Available in 420mm inline only and three common diameters.

This Thomson Elite Seatpost is over 40% stronger on ultimate strength tests than the strongest production seatposts on the market and has over double the fatigue life of any other production models they tested. The tube and head of the Thomson seatpost are integral-machined from one single piece of high strength 7000 series aluminium. The head is not pressed or bonded in, allowing for superior strength and minimum weight. Every component of a Thomson seatpost is 100 percent American made, this includes all fasteners and forgings.

The seatpost is lightweight and the natural ellipse bore inside the tube provides the optimum strength to weight ratio. Thomson Elite seatposts also feature a long 1.614 inch (41 mm) seat rail grip length, helping to prevent seat rail bending from impact loads. Most other branded seatposts have shorter grip lengths than Thomson.

The Thomson Elite seatpost design incorporates a bending fuse to prevent catastrophic failure. All other branded seatposts they tested, every one of them, resulted in a catastrophic failure of the seat and clamp components, with pieces of the tube and head flying off in all directions. This type of failure would dump the rider so Thomson designed a seatpost that 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 clamp at about 250 foot-lbs of torque, all other branded posts they tested flew apart at less than 150 foot-lbs of torque. Under severe impact the Thomson seatpost would bend slightly and allow the rider to come to a safe stop or finish the ride. The designs and materials have passed extensive life and ultimate strength tests and every production lot of seatposts will have ultimate strength and fatigue tests performed. Their on going testing program ensures that every production lot of seatposts meets Thomson's standards.

Adjustments can be made to the tilt of the seat without moving the seat forwards or backward, with infinite tilt adjustment from minus 5° to plus 29°. Very low profile clamps result in zero seat interference, with the swivel nuts located down between the seat rails. All Thomson seatposts also have all parts captive and can easily be attached to a seat without disassembly.

What Mountain Bike Review
Score: 4.5 / 5
"A classic, reliable benchmark seatpost available at a very reasonable price...If you’ve got an unusual or old frame with an obscure seatpost size, Thomson should be your first port of call. The Elite is available in dozens of sizes, so you’ll be able to get one for that 1990s Fat Chance... Other posts have picked up some of Thomson’s features, but the Elite is peace of mind in seatpost form."
