Bikes that live up to Marin's “Made For Fun” tag! The San Quentin range started with a bike developed from the Alcatraz jump bike, with 27.5 wheels, gears and a bit more room to make a hardcore hardtail trail bike. The current version pushes the hard core hardtail ethos a bit further - slacker head angle for descending confidence and a steeper seat tube for efficient climbing.
New to the range are 29" wheel options, for confidence inspiring roll-over.
