Trek Marlin 4 Hardtail Mountain Bike 2022 in Pink

Season:2022

Brand:Trek

Code:297592022PNK

The Trek Marlin 4 is a trail-worthy daily rider that's perfectly suited for everyday adventures, on and off the trail. A suspension fork, 21 speeds and mounts for a rack and kickstand make it an ideal choice for new trail riders or anyone looking for a comfortable, stable commuter with the ruggedness of a real mountain bike.
The Marlin 4 features a lightweight aluminium frame with internal shift cable and brake hose routing to protect your cables and add to the bike's sleek look and a suspension fork that takes the edge off bumps and rough terrain. The smaller frame sizes (XS and S) have short-reach brake levers that make it easier and more comfortable for riders with smaller hands to brake confidently and a curved top tube and a lower standover height that makes it easier for smaller riders to mount and dismount, so you get a bike perfectly moulded to your size.

This versatile hardtail delivers a great ride for all your adventures, but also doubles perfectly as a commuter bike so you can get the best of both worlds!

Key Features & Benefits:

SR Suntour suspension fork: For comfort and control.

Mechanical disc brakes: For reliable stopping in all conditions.

Shimano 21 speed gears: To get you up the steepest of hills.

Please Note: Marlin models in XXS, XS and S frame sizes have a curved top tube and a lower standover height that makes it easier for smaller riders to mount and dismount.
