THOMSON
"Said to be the best on Market
The best there is, and few would argue. There is no better stem or post for your bike than a Thomson. When Thomson claim their stems and seatposts are the strongest available, it's no idle boast. Thomson test like no other manufacturer. They know their products are 40% stronger than their competitors. You can be sure of a Thomson.

"Thomson Seat Posts
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.
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.
Thomson Stems
All Thomson Stems can be flipped and run opposite their stated rise (upside down) giving you more fit options.
The Thomson stem is machined from 7000 series aluminum. The stem is one-piece design with no welds or joints.
The wide clamp length (48mm) and the patent pending undercut around the handlebar combine to grip the handlebar more securely. Thomson's ""two clamps in one"" design provides a stiff ride with minimal flexing or squeaking.
The stem is designed to be very knee friendly. The rear of the stem has no lumps, grooves, or exposed bolts to hit your knee on.
The steerer tube clamps pamper your steerer tube. The clamps have a large surface area and go around the steerer tube more than 180°. The two bolts provide an extra level of security.
The Thomson stem has passed extensive life and ultimate strength tests.
We have an on going testing program to insure that every production lot of our stems meets Thomson standards.
The center tubular section of the Thomson stem is tapered with a constant wall thickness resulting in a high stiffness to weight ratio. The torsional rigidity of the Thomson stem is over 155 foot pounds per degree, the highest of any stem we have tested.
The bolts are custom-made from high strength steel. A corrosion-preventative plating is added to prevent rust. All six bolts are interchangeable. A 4mm hex wrench will fit all bolts on our stems and seatposts.
The stem is annodized to prevent corrosion, and maintain a nice appearance. Thomson stems are available with either a black or clear anodize finish.
The Thomson logo is applied with a laser, so it will not rub off. Most laser marking processes cut through anodize, and will allow the aluminum to corrode. Thomson's laser marking process is specially designed to maintain the integrity of the anodize.
Lightweight - 110mm stem weights approximately 199 grams.
Every component of the Thomson stem, including the fasteners, is 100 percent American made.
The Thomson stem is designed to have the best combination of stiffness, lightweight, strength, and durability.
