Thomson Elite Seatpost Black 27.2 mm x 330 mm
  • 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 catastrophic 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.
  • 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 degree and plus 29 degree.
  • 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.
  • Thomson

    Other Thoughts

    This is my attempt at tweeking my bikes for the most comfortable position. In this case using a 0 degree set back seat post to feel less stretched on the bike as I've had some neck discomfort in the past. I've put this type of seat post on all 3 of my bikes which are all road bikes with drop handlebars. The 31.6 mm went on the Motobecane and I don't use this one for commuting just every third weekend ride which is over 70 miles. I've done one of these rides on this bike so far and did not have any issues. How much more comfortable is it to be 1" closer to the handlebars it's hard to say because I'm always shifting back and forth in the seat anyway so there is no constant. Generally with me when I'm riding along with the wind at my back nothing hurts then when I'm fighting a head wind for miles and miles things start to hurt... go figure. I installed the 25.4 mm on the 75 Royce Union and a 27mm on my 03 Trek. All and all and with other adjustments I've made I'm more comfortable now than I've been in the past especially on the Trek. One note possibly because these posts have a smooth finish. The one I installed on the Royce Union which has a seat post clamp that is part of the frame the seat post will rotate about .25" during normal riding which is not a big deal so long as it does not slip down which it hasn't so far. Set up is a personnel thing and a 0 degree set back seat post is something you can try it you feel a little stretched out on your bike

    This is the third Thomson post I have owned over the past two decades . It replaces a 30-year old post (different brand) on my old Litespeed Unicoi mountain bike. I love the workmanship, reliability and aesthetics of this post. I am confident it will outlast the bike and me too! Worth the cost.
