The Piedmont Frameset

$2,795.00

Say hello to your new titanium gravel bike – the Thomson Piedmont Frameset. You guys asked, and we delivered. Now you can get just the frameset.

The Piedmont frame model comes with a Thomson seatpost collar, Cane Creek Headset, and Columbus Futura Cross+ Fork – everything you need to get started on your custom bike build.

Titanium Frame Construction

The Piedmont gravel frame is built from 3Al-2.5V aircraft-grade titanium tubing. This titanium frame material is known for its strength, corrosion resistance, and long fatigue life. It provides a comfortable ride feel by absorbing vibration while keeping the front triangle stiff for efficient power transfer.

Geometry and Handling

A 70° head tube angle creates stable handling on flats and predictable control when climbing or descending. The geometry is designed for long-distance gravel riding, mixing comfort with responsive steering for both endurance and performance.

Tire Clearance and Chainstays

The Piedmont offers clearance for up to 47c tires, giving riders flexibility for a range of gravel or mixed-surface setups. With 428mm chainstays, the frame balances stability with quick handling, making it suitable for gravel racing or everyday riding.

Drivetrain and Mounting Standards

Equipped with a 68mm T47 bottom bracket shell, the Piedmont works with modern cranksets, including 30mm and DUB spindles. The frame uses a 142×12 thru axle for rear wheel stiffness and includes a replaceable derailleur hanger. Full internal cable routing keeps the frame clean and protected, with many mounting points for bottle cages, fenders, bags, and other accessories.

Aerospace Engineering Meets Bike Performance

Founded in 1981, L.H. Thomson began as a precision aerospace machining company in Macon, Georgia. In the mid-90s, that same expertise was applied to cycling, starting with the iconic Thomson Elite seatpost. Today, every frame, stem, handlebar, and seatpost is crafted with the same standards trusted in aerospace, delivering performance and reliability that riders depend on.
