Trek Marlin 5 Gen 3 XC Mountain Bike in Power Surge

Season:2025

Brand:Trek

Code:40773GRN

Marlin 5 is a trail-worthy daily rider that's perfectly suited for everyday adventures, on and off the trail.

It features a trail-savvy frame with a suspension fork, 9-speed Shimano CUES shifting and mounts for a rack and kickstand that 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 Marlin Gen 3 gives you serious trail capability, with big tyre clearance and slack, confidence-boosting geometry that keeps you stable from singletrack to city
  • Rack and mudguard mounts make it easy to accessorise, so your mountain bike can double as a rugged commuter
  • Its ThruSkew system is safer, simpler and stronger, plus it makes removing the rear wheel easy for flat fixes in a hurry
  • Internal routing makes it easy to add a dropper post that lets you lower your saddle on the fly for more confident descending
  • Marlin models in sizes XXS and XS have a curved top tube and lower standover height that makes it easier for smaller riders to mount and dismount
