Endeavor frame guide
Introducing the all-new Endeavour Titanium Gravel Bike from Airborne. Named for the spirit of bold exploration and discovery, the Endeavour represents the pinnacle of Airborne’s aviation heritage and our dedication to titanium engineering and manufacturing excellence. Designed to go anywhere and do anything, this premium titanium machine delivers refined performance and unmatched versatility across pavement, gravel roads, technical trails, and remote off-road adventures.
Equipped with the innovative RideDNA™ headset system with up to 13 position adjustable head tube angle, it is designed for riders who demand a bike that can be precisely tuned to their riding style and the terrain ahead — without ever compromising the classic Airborne titanium character.
What can be adjusted?
Adjustable headset; fixed dropout/track.
Exploring a frame in RideDNA does not imply adjustable frame hardware. Tire and compatible fork choices can be studied in software, but the frame’s headset and dropout capabilities remain those listed above. Confirm fork compatibility and physical tire clearance with Airborne before changing components.
Frame features
Key features:
RideDNA™ Dynamic Customization™ hardware; 13 position adjustable headset system — modify head tube angle for optimized stability, agility, or all-terrain confidence. Adjust to match your preferred trail preference or normalize your geometry for a longer suspension fork.
Advanced hydroformed titanium T/T and D/T — precisely engineered shapes for superior stiffness where you need it, compliance where you want it, and a strikingly modern, aggressive aesthetic.
SLM 3D Printed Grade 5 (6Al/4V) Titanium, Vacuum Annealed frame components:
UDH Dropouts
Headtube
Dual Dropped Chainstay Yoke
Generous tire clearance — of up to 54mm, ready for fast-rolling gravel tires or high-volume adventure setups
Adventure-ready frame mounts — 4 sets of adjustable W/B or Bag mounts, perfectly equipped for bikepacking, racks, fenders, and long-distance exploration.
Dropper post compatible 31.6mm native seat post diameter or convert to a 27.2mm complaint Ti or Carbon post with the included seat post shim adapter.

Recorded frame geometry
Values below come directly from this Airborne model’s size records, including CAD reference stack, reach and wheelbase where recorded. Angles and BB drop use the size-specific value, falling back to the model baseline. Values are not an engine-generated setup or a guarantee of comparison eligibility. Missing measurements remain “Not recorded.”
