Distinguishing features
One of the pedals was slightly warped (i.e., not fully level). A paper clip was attached to the housing of one of the brake or derailleur cables. There no longer were reflectors attached to the pedals. The wheels had 2.0" Forte inner tubes. All the other parts were original to the bike: Shimano Altus derailleur and shifters, Promax disc brakes, RST fork, dual suspension, etc., most of them exhibiting wear and tear from two years of use.
