Wow, a “used” bike price for a bike that was “used” for about 10 minutes.
This is a 56cm Surly Steamroller, built up as a speedy road machine.
This one has a flip/flop Surly hub so you can alternate between fixed gear and coasting down hill (or run two different gear options). The rims are brand new, and the wheels are fast and tough.
This is a large size bike, and it will fit a rider between 5’8” and 5’10” the best. All yours for $699
