Yaupon Titanium - Drop Bar Mountain Bike - All Terrain Bike
While we recently launched the Yaupon steel, our early Yaupon prototypes were made for team riders in titanium. After balancing their feedback and planning out a range of customizable options we are excited to offer the Yaupon in Titanium as well!
We always say the best bikepacking bikes are the ones you reach for on any given trail ride. The Yaupon is about making big possibilities into reality. An adaptable geometry and broad component compatibility will leave you enjoying this ATB on everything from singletrack to multi-day bikepacking, or a long gravel grind. Build with a drop bar or a mountain riser!
The Yaupon stands out from other bikes in the all terrain bike category with its 120mm fork capability and big tire clearances. Our slacker head tube angle and longer reach are designed for use with a shorter stem & wider bars. We’ve been thoughtful to balance the geometry for off-road riding and singletrack. Throw on a rigid fork and you’ve got an ideal setup for racing routes like Tour Divide or the Unbound XL. The Yaupon represents our thoughts on what makes the most comfortable all day bikepacking bike that can still shred on any trail ride. Scroll down to order or see more.

The Yaupon Titanium is at home tackling technical trails, but foremost it’s meant for the longest rides in the most comfortable and fun way possible! Featuring:
A slack 68º head tube finds the flow in rough terrain.
A steep seat tube angle and other geo numbers combine to keep the front end planted under difficult climbs.
A balanced bottom bracket is positioned to bring out the rest of the geometry and plant the bike in corners whether seated or floating.
The bike is spirited out of the saddle and rather huckable in the tech, but the comfort of the design allows for a long day seated.
The wheelbase offers great maneuverability picking lines on the trail and threading through tight corners.
Tune-able ride quality, each order receives a consultation to plan your frames tubing to optimize your ride experience.

Made in USA quality, handmade to order.
S-bend seat-stays are custom diameter to each frame size for the smoothest ride.
Titanium 3/2.5 Aerospace Grade Domestic Tubing throughout
PMW hooded sliding dropouts offer 20mm of adjustable wheelbase/chainstay length.
Clean thoughtful cable routing along with top tube bag mounts & cargo cage mounts under down tube.
Flawless frame miters, all tubes are heat sunk and argon purged when welded to prevent distortion and material thinning.
Machined head tube for tapered or straight forks.
Many frame customizations available.

What is an All Terrain Bike (ATB)? To us it represents a bike that is designed with all terrains in mind. For the Yaupon this means starting from a solid singletrack ready MTB platform and adding various geometry features to make the bike effective to ride on other surfaces. Singletrack, jeep trails and gravel or fire roads, the Yaupon is thought out to be a fun and effective tool for all these formats. Bonus is the ability to swap between drop and mtn handlebars. On any given bikepacking trip you might find yourself on all these different terrains, so the bike should be designed to perform on them all.

Standover/Effective Seat Tube Angle
Standover is measured 90mm forward of the bottom bracket, using a 29x2.25 tire for reference.
Effective seat tube angle is calculated from average saddle heights and placements per size.
The range is roughly 1º in either direction of the effective angle based on your chosen saddle placement.
Yaupon, pronounced (yo-pawn) or (yaa-pn) is a type of evergreen holly tree found throughout the Southeastern US. It is one of only 2 endemic North American plants that can be used as a caffeine source. It also is a burly hill here in Austin, TX where once crested you can enter into one of the most challenging trail systems named Thumper.
