Built with input from freeride legend Matt Jones, the Marin San Quentin JR24 brings true hardcore hardtail attitude to young shredders. Inspired by the dirt-jumping DNA of the Alcatraz, it’s designed to go further, ride faster and give kids a real taste of progressive trail riding.

Key Features:
  • Series 2 aluminum frame delivers strength, durability and responsive handling for confident trail progression.
  • Manitou J Unit 100mm air suspension fork offers lightweight performance and full adjustability tailored for lighter riders.
  • 1x9 Shimano CUES drivetrain provides smooth, reliable shifting with enough range for real climbs and fast trail sessions.
  • Kid-specific hydraulic disc brakes ensure powerful, controlled stopping with levers designed for smaller hands.
  • Tubeless-compatible tires enhance grip, reduce flats and boost confidence on rough terrain.
  • One-piece seatpost and saddle design lowers standover height for better control and easier handling.

Who is it for?
Perfect for young riders ready to level up into serious trail riding — kids who want a bike that feels just like a full-sized mountain bike, but built precisely for them.
