The San Quentin 24″ will feel like a ‘grown-up’ mountain bike to your little ripper, with a strong Series 2 aluminum frame, 24″ wheels, and, for 2025/26, a new Manitou J Unit 100mm air suspension fork, which means more flexibility for lighter shredders.
Additional changes include a one-piece seatpost and saddle for a reduced standover and riding height, a single 9-speed Shimano Cues transmission, tubeless-compatible tires, and kid-specific hydraulic disc brakes. marin bike
