Yaupon Titanium - Drop Bar Mountain Bike - All Terrain Bike

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.

Available in 2 chainstay styles:

Why Choose the 3-d Space Yoke (Made in USA)

Use this for the most responsive ride quality. This works best for those who like to get rowdy, carry more weight on the bike or want the most performance out of every pedal stroke. Fits a 29x2.6” tire. This option is designed for those who prefer to ride mtb style trails. The Yoke is 6/4 Ti and the chainstay is 3/2.5 Ti so it is stiffer then a full 3/2.5 tube.

Why Choose Columbus Hyperion Ti double butted oval chainstay? (Made in Italy)

Use this for the smoothest ride experience. The full tube is 3/2.5 titanium so it has more compliance built in and for a lighter rider or those not tackling as rough of terrain it can provide a supple ride quality. Fits a 2.4” tire. This option is designed for those looking for a big tire gravel bike. Best Paired to rigid or 100mm travel forks.

All of our complete bikes are built with a custom selection of components. We pride ourselves on listening, understanding your riding goals & working with you to craft the perfect blend of components & customizations.

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.

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.
