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.
