• We chose tubing for comfort in the s-bend seat-stays and subtle sloping top tube.

• Strong chainstays, down tube and an external butted seat tube create a bike that accelerates fast.

• This balance of strength and suppleness paired to the Terlingua’s geometry is designed track through rough terrain.

• Size specific bottom bracket heights fine tune the balance point for cornering to maximize fit performance.

• Tubes are built of the best tubing available & selected per size to maximize optimal ride quality with smooth and predictable compliance.

• The Terlingua steel is designed to perform on long endurance gravel rides and races across varied terrain.

• Fabricated in the USA with machined HT, threaded BB, and Sliding dropouts.

• Chumba Oversized Select Double Butted Tubing and stainless steel sliding dropouts, mean this bike will exceed your expectations and provide years of reliable gravel service.

• Machined head tube for tapered & straight steerer forks

• S-bend Seat-stays and chain-stays for maximum tire and chainring clearance.

• Clean thoughtful cable routing that is adaptable for a clean aesthetic.

• Stainless steel braze-ons.

• Flawless frame miters, all tubes are heat sunk and argon purged when welded to prevent distortion and material thinning.

• Many frame customizations available

• Top tube bag mounts included

Now available in two tubesets! Our Chumba Oversized Select Double Butted Tubeset has always been trusted for trail riding, bikepacking. Prized for its value, dent resistance & balance of compliance/strength.

For those looking for a more race performance tubeset we offer a Velospec Heat Treated (USA made) Tubeset. Available in the frame customizations as an add-on. For lighter frame weight and increased performance characteristics. The tubing is air hardened at weld zones which increases its fatigue strength and resistance to external forces. While heat treatment adds strength, these tubes offer increased elongation % for a compliant ride. The stuff of magic? We think so.
