Thomson Elite Layback 330mm 27.2 Seatpost
The Thomson Elite seatpost is the standard by which all other seatposts are judged. Forged clamps, integrally machined head, and an elliptically extruded 7000 series aluminum body make the Elite an industry standard. The Thomson Elite Layback has over double the fatigue life of any production models 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.
The Thomson Elite Layback has a long 1.614 inch (41 mm) seat rail grip length. This helps prevent seat rail bending from impact loads. Most other seatposts have grip lengths of .500 inch or more shorter than Thomson's grip length.
The Thomson seatpost design incorporates a bending fuse to prevent catastrophic failure. 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. Under severe impact the Thomson seatpost will bend slightly and allow the rider to come to a safe stop or finish the ride.
I have run thomson elite seatposts both layback and straight on most of my bikes. They are the perfect seatpost for any application. The never loosen, move, creek. They stay put and keep you safe. Spend the extra money and get the last seatpost you will ever need.
This seatpost is light and strong, and the legendary Thomsen machining and quality is second to none. I bought the 410mm version due to my long inseam, and it's hands down the best post I've owned. The way it slides in the seat tube without sticking or binding is really appreciated, as I don't like to use a lot of grease on the post due to possible slippage issues. Finally, the easy-to-dial-in clamp is the best; it's infinitely adjustable with two simple bolts. Great product!
