DESCRIPTION

Over 40% stronger on ultimate strength test than the strongest production seatposts on the market.

---

Over double the fatigue life of any 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.

---

Certified to: EN 14766 2006 MTB and DIN CERTCO: 2006 MTB

---

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 other 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 competitive seatposts we tested failed catastrophically with the seat and clamp components, and sometimes pieces of the tube and head flying off in all directions.

---

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.

---

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 means no seat interference as the 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 has ultimate strength and fatigue tests performed. Our on going testing program ensures 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.

FAQ

Q – What colors are Thomson seatposts available in?

A – Black or Silver (Certain sizes available in black only)

Q – Are you going to add other colors in the near future?

A – No, we are not planning to add new colors.

Q – Can I use oval and/or oversized saddle rails?

A – Saddle rails from 7 x 7mm up to 7 x 10mm will work with Thomson seatpost clamps.

Q – May I use carbon saddle rails?

A – Yes you may.

Q – Can I flip my set back post around to be a “set forward” to use my road bike for triathlon?

A – Yes you may. You may need to turn the top clamp to face the front of the bike for saddle adjustment.

Q – How much lighter is the Masterpiece than the Thomson Elite?

A – 40 grams on average.

Q – Should I grease my seatpost before installation?

A – A very light coat of grease is okay. Do not use anti-seize as it can lead to slipping. To prevent sticking the post in the frame, remove clean and re-install every 90 days. Do not use grease in a carbon fiber frame.

Q – Is there a weight limit for the Elite seatpost?

A – Practically speaking, no.

Q – May I bolt a rack or trailer to my Elite seatpost?

A – Yes you can if the clamping mechanism is sized to the outside diameter of the seatpost and has a round, not oval clamping mechanism. Do not try this with the Masterpiece Seatpost.
