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.

Discover

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.

Discover

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.

Is the Piedmont only a gravel bike?

The Piedmont was designed as a titanium gravel bike, but its geometry also makes it comfortable for road riding or light single track. If you’re looking for a dedicated setup, check out our full lineup of mountain bikes and road bikes for more options.

What tire clearance does it have?

The Skeeter supports up to 28c tires, giving you flexibility between fast-rolling track setups and slightly wider tires for street riding.

Does it support a suspension fork?

Yes, the carbon fork included is rigid, but the frame is compatible with certain short-travel suspension forks for added versatility.

What bottom bracket standard does it use?

The Piedmont uses a 68mm T47 bottom bracket, offering stiffness and compatibility with 30mm spindles and modern cranksets.

What frame sizes are available?

The Piedmont is available in XS, S, M, L, and XL. Geometry is listed above to help you choose the right fit.

How does titanium compare to a steel gravel bike?

Titanium offers a lighter weight and naturally smooth, compliant ride quality. It’s also corrosion-resistant, giving you a frame built to last a lifetime.

Can the Piedmont be built into a complete bike?

Yes. While the Piedmont is sold as a frameset, we offer a Gravel Build Kit that allows you to turn it into a complete bike. Riders can choose from a range of custom options, including stems, handlebars, and seatposts, to create a setup tailored to their riding style. If you are looking for a complete, ready-to-ride build, just reach out, and we would be happy to help.
