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 most likely only offer them once a year (We are now on our second production run of frames). If you appreciate the lighter weight, corrosion resistance and dreamy ride quality that titanium offers then the titanium version of the Stargazer is a great option. 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. 

Geometry is the same as the steel frame, with 1cm longer in the top tube on all sizes.

    How can I run 11 speed SRAM road shifters with a 12 speed SRAM Eagle drivetrain?
    A company called Ratio Technologies produces a kit that converts SRAM 11 speed road shifters to work seamlessly with 12 speed mountain derailleurs, we use their kit on our complete builds.
    Can I run flat bars on the Stargazer?
    Yes, you'll just need to take into account that the frame has a reach that is optimized for drop bars, you'll likely need a long stem to run flat bars.
    My flat mount brake adaptors only have the option for 140mm or 160mm, what setting do I use for the Stargazer?
    For the rear brake,if you want to run 160mm rotors, mount the caliper directly to the brake mount. Use the 160mm rear brake adaptor to run 180mm rotors. For the front brake, use the 140mm setting on your adaptor for 160mm rotors, and the 160mm setting for 180mm rotors.
