The Trek Marlin 5 Gen 3 Mountain Bike is right where you need to start – packed with features to get you off the beaten track and into new territories. Adapted for each size, the lightweight aluminium frame will accommodate smaller riders with a curved top tube and lower standover height, paired with Smart Wheel Sizing that ensures you’re shredding with the fastest wheel that fits, shorter reach brake levers and narrower handlebars so however small the rider, they maintain effortless confidence and control. Trek has updated the 9-speed Shimano CUES drivetrain with LINKGLIDE technology to increase the lifespan on wear-prone components such as the chain, cassette and chainrings so this workhorse just keeps on going. Whether on the trail or riding on the tarmac, the Marlin 5’s hydraulic disc brakes will make sure you’ve got efficient stopping power whatever the conditions, and a suspension fork with travel up to 100mm will help smooth out the terrain ahead of you. If you’re planning to be out for most of the day, rear kickstand mounts, rack mounts and the Bontrager Blendr stem tech where you can clip gear directly to the stem, means you’ve got plenty of options for keeping supplies with you for the long haul. Gear up and get out on the bike whether you are dipping your toe in MTB adventures, looking for a beast to cruise you through the commute or simply wanting to snap up a deal, the Marlin 5 Gen 3 has plenty to offer without breaking the bank. The 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.
