Trek Marlin 4 Gen 3 MTB in Matte Dark Web

Season:2026

Brand:Trek

Code:57361BLK

Marlin 4 is a trail-worthy daily rider, perfectly suited for everyday adventures, on and off the trail.

This bike features a trail-savvy frame with a suspension fork, 8-speed Shimano ESSA shifting, and mounts for a rack and kickstand. These features make it an ideal choice for trail riders or anyone looking for a comfortable, stable commuter with the ruggedness of a real mountain bike.

Features:

  • The frame design allows for a lower standover height, which benefits shorter riders by making it easier to straddle the bike. Larger frame sizes have a straight top tube, as taller riders typically do not have the same standover height issues.
  • Marlin comes in seven frame sizes to suit riders of any height, and Smart Wheel Size ensures you are on the fastest wheel that fits. The smallest sizes even come with short-reach brake levers and narrower handlebars that give smaller riders better comfort and control.
  • Marlin looks and feels great. It is packed with features usually found only on more expensive bikes, like a stylish frame with internal shift cable and brake hose routing, which can help cables last longer by protecting them from the elements.
  • Inspired by rider demand for trouble-free drivetrain longevity and performance, Shimano CUES offers a new foundation for versatility and durability across a range of both electric and standard bikes. CUES features Shimano’s new LINKGLIDE drivetrain technology for significantly increased life on wear items like chain, cassette, and chainrings.
