Will completed the challenge a 2nd time today with a very unimpressive clunker 29er not super vintage but about 20 years old, clunky , heavy and ugly with pretty every feature we here at the forums tell people to avoid in used bikes. Bad paint, cheaper suspension fork, cheap disk brakes, women's frame, wrong size and general junky vibe. This one will likely be going back to the thrift store in the next day or so.
