Frames are in stock and shipping now. Production frames have dark decals and a dark blue fork.
Introducing our new Stargazer drop bar mountain touring frame in titanium with a steel fork. It's a super high end frame with multi-butted, cold formed oversized custom 3Al-2.5V tubing that stands up to loaded off-road riding without turning into a noodle. We've been riding the sample frames for the last year and it's the bike I reach for more than any other. This is a super limited production frameset, we will have a total of 25 frames split between all the sizes, and at least two of them are spoken for by Tumbleweed employees. This may end up being a one time deal, so if you appreciate the lighter weight, corrosion resistance and dreamy ride quality that titanium offers then this could be a good bike to consider. We will sell these as framesets as well as complete builds, if you are interested in a complete bike please let us know in the notes section at checkout.
