Trek Roscoe 8 Gen 4 MTB In Dark Star

Season:2026

Brand:Trek

Code:59872BLK

Built for a good time from the ground up, Roscoe is a rowdy hardtail here to party.

Progressive trail geometry keeps it lively and confident while 29˝ hoops with plenty of tire clearance give you grip to rip through the rough stuff. Up front, a mid-travel suspension fork soaks up roots and rocks, and keeps handling smooth when the trails get wild.

The Roscoe 8 is a rowdy hardtail built to hunt for side hits and dive into the steep stuff. Its Alpha Platinum Aluminum frame pairs with a Fox Rhythm 36 fork (150mm travel) to soak up rough and chunky trail debris. It delivers plenty of gears for punchy climbs, thanks to a 12-speed Shimano Deore drivetrain, and stop-on-a-dime braking power from 4-piston Shimano M6100 hydraulic disk brakes.

Features:

  • Ready to get rowdy with 150mm front travel, trail-smashing 29-inch wheels, and dialed-for-dirt frame features.
  • Rock Solid: The bolt-on downtube guard will stay put even after ripping through a chunky trail, keeping the bike quiet and protected.
  • Integrated storage: The frame bag is made from a recycled ripstop polyester with an eco-friendly DWR coating that is water resistant, with plenty of room to stash everything from snacks to safety supplies.
  • Progressive trail geometry: A long reach, slack head angle, steep seat angle, and short chain stays combine for a ride that's confidence inspiring, yet still nimble and fun.
