Product Overview
The Stargazer is "a nimble and balanced drop bar mountain touring bike designed for loaded trail riding" and is the second offering from the Tumbleweed Bicycle Company. Following in the tire tracks of the expedition-focused Prospector, this new model shares similar high-end, heat-treated Cr-Mo tubing and mountain bike geometry but in a package built around drop bars and a 1x derailleur drivetrain. This may just be the off-road drop bar bike you've been waiting for!
We're pleased to offer the Stargazer in a Bike Touring News exclusive color: Rainy Sage! This color will not be available anywhere else and quantities are limited. There will be no more frames in this color after this small production run is sold out, so don't drag your flip flops!
Inventory
Framesets are in stock and ready to ship. Quantities are extremely limited and there will be no more of this color produced. Don't drag your flip-flops!
Shipping
Framesets will ship for a flat $35 fee to addresses in the continental USA. Please contact us for a shipping quote outside the lower 48. International shipping is not available. We suggest that international customers work with a Tumbleweed dealer in their region to purchase a frameset.
