A Wild and Playful Hardtail Ready to Rip

The Trek Roscoe 7 Gen 4 is a wild and playful hardtail that is ready to rip anywhere from rowdy singletrack to dirt jumps. Its Alpha Platinum Aluminum frame pairs capable geometry with a RockShox Recon Silver fork with 150mm of travel for gobbling up rocks, while a 10-speed Shimano CUES drivetrain provides low-maintenance, clean shifting. It is finished with 2-piston Shimano MT200 hydraulic disc brakes for reliable all-weather stopping power. This listing is the Medium (17.5 inch) frame.

With 150mm of front travel, trail-smashing 29-inch wheels and dialled-for-dirt frame features, the Roscoe is ready to get rowdy on your favourite rides.

Progressive Trail Geometry

A long reach, a slack head angle, a steep seat angle and short chainstays combine for a ride that is confidence-inspiring, and still nimble and fun. This is modern trail geometry on an affordable hardtail.

Medium geometry: 611mm effective top tube, 440mm reach, 644mm stack, 65-degree head angle, 75-degree effective seat angle, 430mm chainstay, 1186mm wheelbase, 312mm BB height, 61mm BB drop, 735mm standover, 125mm trail, 100mm head tube, 375mm seat tube, 44mm fork offset.

Rock Solid

The bolt on downtube guard will stay put even after ripping though a chucky trail, keeping your bike quiet and protected.

10-Speed Shimano CUES and Hydraulic Disc Brakes

The drivetrain is a Shimano CUES 10-speed group, with a U6000 shifter, CUES U6000 GS rear derailleur, a 30-tooth chainring on 170mm cranks and an 11-48 LINKGLIDE LG300 cassette. Shimano says LINKGLIDE is built for low-maintenance, reliable shifting. Shimano MT200 2-piston hydraulic disc brakes with 180mm centerlock RT10 rotors give reliable all-weather stopping power.

Safety note: Check the brakes, tires and dropper post before each ride, wear a helmet and protective gear for rough trails, and have the bike assembled and serviced by a qualified mechanic.

Integrated storage

The frame bag is made from a recycled ripstop polyester with an eco friendly DWR coating on the outside that is water resistant, with plenty of room to stash everything from snacks to safety supplies.

RockShox Fork, Dropper Post, and Wheels

The RockShox Recon Silver RL fork has a Solo Air spring, a Motion Control damper and a lockout, with a tapered steerer, 42mm offset, Boost110 spacing and a 15mm Maxle Stealth axle. A TranzX dropper seatpost with 170mm of travel and internal routing lets you drop the saddle on steep descents.
