Terlingua Steel Gravel Bike

The Terlingua is a high performance gravel bike, capable of traversing long distances on a wide range of surfaces. The geometry is also at home sprinting out of corners at your local cyclocross race. The Terlingua represents the best in modern steel bike design with a low frame weight & a team tested tubeset selected for performance. Features like stainless steel sliding Paragon Machine Works dropouts w/ replaceable inserts, industry leading compatibility for tire clearance, chainring size and drivetrain styles mean the Terlingua will find a home in your bike stable for years of service. The Terlingua steel comes in a full range of sizes from 50-60cm and fit true to size. Made in USA quality, built in house in Austin, TX.

    • 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.

    • Made in USA quality, built in house in Austin, TX.

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

    • Tapered EC34/EC44 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.

  • 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.
