San Quentin 1
Marin
Trail
San Quentin 1 is an alloy trail mountain bike (2025), from Marin, part of the San Quentin family. This model is best for riders looking for a balanced off-road setup, with a setup that gives you a balanced riding position, and is well suited to natural trails and mixed off-road terrain. Its profile is strongest in areas like strong value-for-money versus many similar bikes, all-round climbing capability rather than a narrow specialty, and capable suspension support for rougher terrain. At the same time, the main trade-off is a firmer ride feel than comfort-first options and less emphasis on outright speed than speed-focused builds.
