Marin San Quentin Jr. 20 Mountain Bike in Yellow/Orange

Season:2026

Brand:Marin

Code:740689001

Designed with the input of freeride legend Matt Jones, the San Quentin takes the DNA of Marin's dirt-jumping Alcatraz and mutates it into a go-further and faster all-round, hardcore hardtail.

The San Quentin 61cm (24") will feel just like a ‘grown up’ mountain bike, built with a stout Series 2 aluminium frame, 61cm (24") wheels, and a Manitou J Unit 100mm air suspension fork, meaning more adjustability for lighter shredders. Further updates include a one-piece seatpost and saddle to allow for a lower standover and ride height, 1 x 9-speed Shimano Cues drivetrain, tubeless compatible tyres, and kid’s specific hydraulic disc brakes.

Features:

  • Shimano 1 x 9 Cues drivetrain
  • One-piece seatpost and saddle
  • Manitou J Unit 100mm air fork
