TrekMarlin Gen 3 MTB Frame Set in Matte Black

Season:2025

Brand:Trek

Code:37982BLK

The Marlin Frame Set is a lightweight aluminium frame ready to be built into the perfect easygoing trail bike.

You are new to mountain biking and want a confidence-boosting bike that is built to handle the trail, and love the idea of putting together your own dream bike build.

A lightweight aluminium frame with internal routing protects your cables and keeps your bike looking sleek, plus modern geometry that ups confident handling in varying trail terrain. Plus, a Thru-Skew rear axle is safer, simpler, and stronger than standard quick-release.

The Marlin Gen 3 Frame Set is made for taking on the trail. The modern geometry is ultra-capable, and added features – like extra tyre clearance and mounts for racks and kickstands – up the versatility.

Features:

  • The Marlin Gen 3 gives you serious trail capability with bigger tyre clearance, internal dropper post routing, ThruSkew rear axle and longer, slacker geometry that gives you more stability on steeper trails and at higher speeds.
  • You will get a lightweight aluminium frame that is robust enough for the ride without weighing you down.
  • Mudguard mounts make it easy to accessorise, so your mountain bike can double as a rugged commuter.
  • Marlin models in XXS and XS frame sizes have a curved top tube and a lower standover height that makes it easier for smaller riders to mount and dismount.
  • Internal routing looks sleek and makes adding a dropper post easy.
