The Stargazer is a nimble and balanced drop bar mountain touring bike designed for loaded trail riding. It's at home on trails, singletrack and gravel roads whether unladen or with racks and bags on an adventure. The Stargazer a direct descendant of Tumbleweed’s first bike model, the Prospector, and shares much of the same tubing and mountain bike geometry, with a shorter reach to accommodate drop handlebars, and a lighter weight overall package. Our standard build combines a 12 speed SRAM Eagle wide range 10-52 tooth cassette and derailleur with SRAM Rival road shifters via a Ratio Technology 1x12 Wide Upgrade Kit, and the left shifter is modified to control actuation of the dropper seatpost.
