The Sunliner is our 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.

Complete Bike Purchase Process

We build complete bikes in the order that build specs are finalized. Our standard build with the parts list as shown is $3775 USD, we use this as a starting point for your build, and since we custom assemble each bike from the frame up including hand building all of our wheels, there is a wide range of changes that can be made to our standard spec. 

Once you place your complete bike deposit, we put your name on the frame/fork and reach out to start confirming the final spec for your bike. Once we have finalized the build spec, we send over an invoice for the final balance due. Once the final invoice is paid, your build sheet goes into our build queue and we begin ordering any necessary parts for your bike. Our goal is to have your bike completed and ready to ship within 4 weeks from the time you pay your final invoice, although there can sometimes be unforeseen delays if a component is out of stock from the manufacturer, etc. 

We build your wheels, completely assemble your bike, test ride it multiple times and double check all adjustments before packing it for shipment. When you receive your bike, we recommend taking it to a professional mechanic for reassembly, it will be very straightforward for a shop to assemble.
