Terlingua SL Titanium Gravel Bike

The Terlingua Titanium SL is our race focused titanium gravel/all-road bike. The frame features the highest caliber of titanium tubing materials and a custom S-bend rear triangle with double butted oval chainstays and a threaded T47 bottom bracket. It can be configured with 1x or 2x, electronic or mechanical drivetrains, or set up singlespeed.

Compared to our other Terlingua models the SL geometry trends towards a more aggressive geo create a responsive race focused geometry. Spirited group ride? Gravel race? That’s what we are after here. Our handmade titanium 3/2.5 tubing frame is a smooth ride. A little comfort equals more endurance on race day. Compliance in the frame keeps you connected to the terrain letting you track through rough corners and descents. Oval chainstays transfer more power through the drivetrain.

We’ve maximized compatibility with tires up to 700x50 and 1x and 2x cranksets. Our sliding dropouts offer a solid platform for adapting your ride feel whether geared or set up singlespeed.

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

    • Reach, head tube and seat tube angles place the rider in an effective position to attack climbs and sprint.

    • The titanium tube-set is tuned for weight savings and responsiveness that accelerates fast with stable handling both climbing and descending.

    • Compared to our steel Terlingua the Titanium frame has similar dampening capabilities, but returns to its original position faster resulting in a responsive feel.

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

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

Why choose the PMW Sliding w/Flat Mount dropout option? (included in frame price)

Use this dropout to gain 20mm of adjustable chainstay and wheelbase. This feature offers the widest range of tire fitment and ride characteristics. The 415mm chainstays position equals a more responsive ride or move it out up to 435mm to make the ride more stable. Both sides of the dropout have replaceable Flat Mount inserts/hangers. Bonus, if the mood strikes, they also allow you to run the bike as a singlespeed.

Why choose the PMW Direct UDH Integrated Flat Mount dropout option? (option in frame customizations +$250)

Use this to gain access to the SRAM Universal Derailleur hanger, “UDH”. Some riders aesthetically prefer the brake caliper mounted on the chainstay. It certainly looks tidy! What you lose in adjustability when compared to the Sliding Dropout is made up for with a lighter weight dropout system.

New options for ENVE In-Route Fork and cockpit kits/builds and we are adding a size 62cm frame to the size options!
