Aaron Barcheck and company build beautiful bespoke bicycles as Mosaic Cycles, in my home of Boulder, Colorado. This is mine. And I love it! It's essentially a Salsa Cutthroat rendered in steel. It has clearance for both the 27.5+ wheels and tires pictured as well as 29" wheels. I have a ridiculous number of bottle mounts thanks to the three on the frame and two more on the Salsa Firestarter carbon fork. There are a few things that set it apart from what you can buy from Salsa though. Dropper post routing is one of them. While I don't have a dropper on it now, I plan on using the port as a way to quickly change between a pair of Di2 batteries. I'm making a custom frame bag for the bike that will have a corresponding port for the wire and an internal pocket for the batteries. Nor does Salsa offer this color, based on San Pelligrino's Blood Orange sparkling soda.
This bike will serve as my bikepacking bike and it's the steed that I'll use next year on Tour Divide. It will also see action in gravel races where I want mega tire clearance with 40mm tires. In a few day's time the Mosaic will experience its first multi-day trip when Kristen and I ride from Grand Teton, north along the Great Divide Mountain Bike Route to Ovando, Montana. From there we'll head to Missoula to fete the 40th anniversary of the Adventure Cycling Association and the BikeCentennial. Can't wait to get out there!
