I worked on this bike last fall and had it tuned up completely at Bicycleistis in preparation for this year, but then went and got a couple of dogs in the winter. I'll be walking instead of biking! It has a new 1x9 drivetrain that I had installed for ease for my wife Tubeless tires are brand new and everything works nicely. I worked at Fort St. Cycle when the Leftys came out, but could never afford them then, so really wanted to have something cool built around it. I also have a separate ad for a Cannondale Lefty Prophet that I did for myself.
