Sold – 20.5″ 2012 Marin Hamilton Urban 29er 2-Speed Bike


Condition: Like new with few minor scratches to paint.

MSRP: $600

Our Price: $350

Worth Noting: This bike fits a bit larger and more upright due to the sloping top-tube. The 20.5″ frame size might fit more like a 22″ or so on a standard-framed bike.
