Roscoe F/S XL 29 Lava

Roscoe Frameset is a build-your-own-adventure hardtail frame thats up to get down. Its Alpha Platinum Aluminum chassis delivers progressive hardtail trail geometry thats confident anywhere from fast and loose trails to dirt jump lines, and is designed to be paired with a 150mm fork. Build it however you dream, then chase down your rowdiest pursuits.

Ready to get rowdy

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

Rock Solid

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

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.

Progressive trail geometry

A long reach, slack head angle, steep seat angle, and short chain stays combine for a ride thats confidence inspiring, yet still nimble and fun.
