The No. 22 Aurora

Blending the responsiveness of our Reactor road race frame with the versatile handling and confidence of the Great Divide, the Aurora is our range-topping model for all occasions.

A top priority when developing the Aurora was to balance high stiffness and crisp handling with all-day comfort levels that only titanium can deliver. Despite an overall stiffness level approaching our race-specific Reactor model, the Aurora is the smoothest riding frame we offer. A combination of carefully shaped and butted tubing, svelte seat stays and the one-piece carbon seat mast result in a frame that smooths vibration like nothing else on the road.

"Sometimes it feels like No. 22 can’t attend a custom bike show without walking away with an award."

CyclingTips, November 2022

"The new Aurora is not so much an evolution but a seismic shift in how bikes - titanium ones, at least - are designed and built."

Available Finishes

All No. 22 frames are finished completely in-house, and are available in a broad range of finish options from classic Raw, to colorful Anodized, to stunning Cerakote and Anodized combinations.

Raw Finish

Every No. 22 frame comes with our Raw finish as standard. We never use stickers or decals for our graphics: the raw finish uses a mix of polished and blasted graphics to show off titanium's natural lustre in a timeless, durable way. Frames with Raw graphics include all of the same graphic details as our anodized finishes, but without the color.
