Tubleweed Sunliner Frameset
The Sunliner is Tumbleweeds newest model, it's a fully rigid mountain touring bike built with the same ultra high end steel tubeset and construction as our award winning Stargazer, but with the geometry from the Prospector that has been optimized for flat/swept back bars like our Persuader. The Sunliner has the same non-suspension corrected fork design as the Stargazer, which creates a huge front triangle and allows for maximum framebag space as well as easy fender mounting. The Sunliner can fit up to a 29x3.0" tire and has all of the mounting points for racks, fenders and gear that you would expect for a bike designed from the ground up for off road touring.
This bike came about due to requests from two different groups of customers, those who wanted a flat bar expedition bike like the Prospector but built around thru axles and derailleurs instead of the 14 speed Rohloff internally geared hub, and customers who love the Stargazer but prefer riding with flat bars over drop bars. We've been riding prototypes of the Sunliner for about a year now in all sorts of configurations, drivetrains, bag/rack setups, loaded and unloaded and it's a very easy bike to recommend to anyone interested in a versatile and capable all around bikepacking rig.
We at JustPedal assemble each bike one at a time and hand build the wheels in house to the customer's specifications. Our Complete Bike Standard Spec is the starting point that we use for each build, and can be changed to suit your needs. The price for a Standard Spec build is about 3800 Euro. Bike delivery times will vary based on availablility of desired components and the number of builds in our queue, the current lead time is approximately 4 weeks for shipping a complete standard build once the parts list is finalized.
