Thomson Elite Seatpost

Ask around about Thomson seatposts and you will most likely hear nothing but positive feedback and accolades. They are informally referred to as the Chris King of seatposts. The clamp design is simple, reliable and easy to adjust. It consists of an upper and lower clamp that is held to the post with two screws. The screws lace through holes that are machined into the head of the shaft, then through the clamps and thread into bolts that rest in the upper clamp plate. It's that simple.

The shaft itself is made from elliptically extruded, machined and anodized 7000 series alloy. The clamp plates are forged and anodized. The plates are 41mm long so they prevent seat rail bending from impact loads. Bolts are steel while the washer and nuts are brass which help inhibited rust and corrosion.

Cosmetically, the Elite is a beauty. The shaft has a micro ribbed texture and etched Thomson graphics on each side of the post. You can get them in either silver or black with many lengths and diameters to choose from. Weights range depending on the post. A 27.2x250mm weights in at 193 grams while the 31.6x367 comes in at a very respectable 227 grams.

    this is the best seatpost out there, period. i wouldn’t trade it in for a lighter, sexier, more expensive carbon job EVEN if someone PAYS me to do it..........well, if someone paid me $200, i’d dump the carbon later and buy 2 more of these thomsons.

    Someone said that this was the "Chris King of seatposts" - that’s the best description of Thomson stuff I’ve ever heard. It’s just the best stuff - light, fantastic adjustment, replacement parts available, and a predictable, non-catastrophic failure mode.

    Have them on all my frames and never have a problem. The ’Chris King’ of seat posts.

    Excellent post... I’ve got three of them on various bikes and I’ve never once had a problem. Only a few grams over their carbon competitors and they’re a fraction of the cost! Great product!

    This seat post is such great value for the money, it is very well made and functional without any gimmicks. The seat rail attachment system is simple to use and easy to adjust as well, with graduated marks for reference.

    The Thomson post is an excellent example of a cycling component being able to be light-weight, durable and inexpensive. It truly is a "set-it-and-forget-it" item. I have them on all my bikes, and never had one fail to deliver perfect performance every ride. There may be lighter or more sexier seatposts out there, but the few grams you save will long be forgotten after spending an hour setting them up (USE alien) or the carbon begins to fail.

    This is a great seatpost. I own a 27.2x250mm silver. Although the post appears to be polished aluminum, the surface is not smooth, instead the tube surface has very fine ’file like’ ridges--this seems to make the post not show scratches from clamping the post (then later raising to a have more post exposed). These ridges may also help keep the post from slipping, mine has never slipped. Within its adjustment range, the post is infinitely adjustable, unlike single bolt posts I have used. The saddle clamps have low clearance, so saddles with little space between the rails and bottom of the seat (like the Selle Italia SLR) can be mounted. The saddle clamps are very rail friendly, no sharp edges and a long rail grip length. The post weight of 228 grams is probably for the 330mm length; I would guess my 250mm is under 195 grams. Note that the seatpost has no set-back; if you need to be further back, Thomson makes a bent post (be sure that you need over 105 mm vertically of se
