Tumbleweed Stargazer (Gen 2) Frameset

The Stargazer is Tumbleweed's award-winning drop bar mountain touring bike designed for loaded off-road riding. It's at home on trails, singletrack, and gravel roads whether unladen or with racks and bags on an adventure. The Stargazer is 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. 

Standout specs: 

• Rigid-specific frame geometry
• Triple- and quad-butted heat-treated Chromoly frame tubing
• Boost axle spacing and tire clearance up to 29x2.6” 
• Built for wide range 1x drivetrains
• Reach optimized for wide drop bars
• New with the Gen 2 model: 10mm longer effective top tube length across all sizes, a 31.6mm seatpost diameter, and a UDH dropout

Tumbleweed's 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. The left shifter is modified to control the actuation of the dropper seatpost.

The Stargazer is built for:

• Riders who need to cover a wide range of terrain, from trails to singletrack and gravel
• Riders who need a versatile model that’s optimized for bikepacking and loaded off-road touring that can swap 27.5+ and 29” wheels
• Riders who prefer drop bars
