welding underwater is v difficult, But our friendly merfolk do the hard work so you don’t have to! Our frames are hand-built around the world, including some right here in the ol’ USA. We offer frames in steel and titanium.

Frame Only

The answer for all of you dirtbags with spare parts piled up in your garage. Our frames can handle most typical suspension forks and common wheel sizes, nothing proprietary here! That’s how we build bikes too, no shame in re-using old parts! But we also know that’s just what you tell yourself and you’re actually going to buy a bunch of new stuff. don’t lie to us.Content here
