The Terlingua Titanium - A New Gravel Bike from Austin's Chumba

Chumba USA, with their headquarters in Austin, TX, has a mission to create your dream bike through careful planning, precise engineering and an elevated user experience. Building MTB, gravel, CX, and “ultraracers”, the company aims to help cyclists reach their goals with their super durable bikes, all made in the USA.

This month Chumba launches their Terlingua Titanium Bike, a Di2 compatible 700c or 650b plus gravel ride that can handle it all.

The Terlingua equipped with an ENVE G-Series Fork

The idea behind the Terlingua has always been to make an extremely versatile bike that can legitimately perform in a wide range of ride styles. To accomplish this we utilized sliding dropouts, carefully planned component compatibility and a fresh race proven geometry. The titanium version is meant to be a lighter and more responsive version of the steel Terlingua’s geo and tubing concept.

The Terlingua’s ability to be built in a range of configurations along with fantastic tire clearance makes for a bike that is truly ready for any gravel event or ride you can throw at it. Thought out features for the rider like a compliant yet race driven tubeset to 3 low mounted bottles for frame bag room and large capacity hydration to mean you can pull big days on the dirt. 


We’ve designed Terlingua in a way that maximizes the abilities of the sliding dropout. Move the dropout rearward to make the bike more stable for long straight roads or when loaded down. Keep it forward for rides with lots of cornering or a CX race. The sliding dropout along with our S-bend stays allow the use of a wide range of tire sizes. Headtube, seat tube angles and BB drop are all mapped out for a balance of high and low speed control while placing the rider in a powerful riding position. 

Frame Features 

  • Covert Di2 integration is neatly hidden out of sight 

  • Sliding Dropouts with short CX length to long big tire gravel length and everything in between. 

  • 425mm to 445mm Chainstay Length 

  • Size specific BB drop to optimize crank arm lengths and rider weight for cornering and high speed gravel descending 

  • Lowest possible mounted bottle cage mounts for 2 bottles interior of down tube leave room for half frame bag options or shouldering the bike with a bottle in the seat tube 

  • Third bottle cage mount under down tube on all sizes 

  • Saves 11oz of weight off of steel model (56cm frame) 

  • Paragon Machine Works under down tube cable guides for 1x/2x/Rohloff and Single speed systems 

  • Thought out cable routing offers smooth shifting and braking, no weird bends or adaptors needed 

  • Down tube cable guides carefully mapped out so they don’t rub your arms during CX shouldering 


Tire Clearance on the Terlingua is up to an impressive 700c x 50mm or 650B x 2.2”. As for crank clearance, she will fit Dura Ace, Sram Red and Easton EC90 cranks (which are all narrow Q factor, so it can clear most any crank), and 53T double or 46T Oval single chainrings.
