A carbon gravel bike for every road

Our Thesis

We created our bikes as an act of rebellion

Introducing the Thesis OB1: a premium carbon gravel bike for any road, from perfect asphalt to rocky trails.

The OB1 is fast, versatile, brilliantly equipped, and built to last. Combine that with our factory-direct pricing, and you’ll understand why it’s been called “unbeatable”.

Chase down roadies and hit the trails on the way back. Pack your gear and disappear for a few weeks. Ride every road that calls you.

What our riders are saying

I fear I have developed a superiority complex because I see all other bikes, especially the $12,000 bling-bling road bikes, as ridiculous now. The impression I have is that if chased no one would ever catch me because I could just bunny hop over the curb and set off into woods before anyone even knew what happened. This bike screams capability.

Patrick G.

Exceeds all expectations. The bike is basically perfect.  Smashed a bunch of PRs with my out of shape for the holidays legs.  Due in part to its just so damn fun to ride. Joy = speed it seems. This thing is a thoroughbred.

Joshua S.

I’m a typical, skeptical mechanic. I’ve worked on and ridden every gimmicky bike in the book. I've never seen one this well thought out.

Aaron C.

Hands down some of the best people. If you’re looking into getting a bike... get in touch with Randall. His business and their mission are truly all about the end user and a flawless end product.

Matt E.

I can’t think of a trail or road where I wouldn’t have a ton of fun riding this bike. I could ride uphill forever on this thing!

Susan T.

Both the front and rear ends felt stiff under power when I needed it, like on the road bikes I’m used to, and it was just so fun to shred fire roads and singletrack.

Marc Mendoza, founder of Post Carry

Damn it. I don’t want to ride my regular bike now.
