- It's more fun to be a better rider: Roscoe is so stable and forgiving, it's like an instant ability upgrade
- Even when the trail gets rough, the wide 27.5x2.8˝ tires can deliver confidence, traction, and stability
- The dropper post lets you lower your saddle on the fly so its out of the way on descents
- The RockShox Solo Air fork can easily be adjusted for a specific rider weight, and it's lighter than a coil spring
- The NX Eagle drivetrain gives you a wider range of gears for easier climbing in a simple 1x set up
"A total ripper"
"Roscoe is a plus-tired hardtail that's decked out with all the modern luxuries you could want. Trek has done a stand-out job with the build kit - positive feedback from the key contact points and a thumbs-up from us. Not only were we impressed by its handling, it featured all the modern conveniences, including chunky 2.8 tires and a dropper post."Read more

Sizing & fit
The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local Trek retailer.
