The Marin Stinson 1 LS in Teal (Medium/27.5") combines the brand’s signature comfort geometry with a bold, retro-inspired aesthetic. The Medium (MD) frame offers a slightly longer wheelbase and higher stack than the Small, providing extra stability for average-height riders.

Component Specifications

• Frame: Series 1 Comfort Low-Step, 6061 Aluminum.
  Features internal cable routing and multiple mounts for a rear rack, fenders, and a kickstand.
• Drivetrain: Shimano 1x7-Speed.
  Utilizes a 38T front chainring and a wide-range cassette (11-34T), providing enough range for moderate hills without the complexity of a front derailleur.
• Brakes: Clark's CMD-23 or Tektro MDM280 Mechanical Disc brakes.
  Uses standard Shimano-compatible pads, making maintenance easy at any local shop.
• Tires: Vee Tire Co. Speedster, 27.5" x 2.35".
  Large air volume allows lower pressures for a "floating" feel over bumps and cracks.
• Controls: Shimano Altus RapidFire shifter (trigger style) for precise, clicky gear changes.

Design Highlights

• The Teal Finish:
  This colorway is often a "Gloss Teal" that stands out significantly more than the Charcoal version. It’s frequently paired with a plush Marin Comfort Saddle and ergonomic Marin Adventure grips designed to prevent hand numbness.
• Comfort Control Geometry:
  The "secret sauce" of the Stinson. By moving the pedals slightly forward and slackening the seat tube angle, Marin allows you to keep your seat high enough for a full leg extension while pedaling, but still reach the ground with your feet when you stop.
• Ease of Use:
  The "LS" (Low-Step) design means the top tube is dropped almost to the bottom bracket, making it one of the easiest bikes to step through on the market—perfect if you're carrying a bag on a rear rack or wearing restrictive clothing.
