Yes. Wood.

Renovo R4 - Hickory, Walnut and Padauk. SRAM Rival group. Rolf Prima Aspin wheels. Alpha Q CS-10 fork.
Rides like carbon fiber because it's all natural carbon fiber!

He-he . . . I LIKE IT! Yes and that's coming from a weldor.

Just curious though, how much does it weigh?

Awesome looking bike! This going to be the new age ?

To be honest, I haven't put it on a scale but the Renovo website sez:
"Frames weigh from 3.5 to 4.5 pounds, depending on size and the particular wood. Complete bikes weigh from 16.5 to 20 pounds depending on components and configuration."
I have no reason to doubt that assessment...

that is awesome! some have to worry about rust, others have to worry about termites......
