Details

Roscoe Frameset is a build-your-own-adventure hardtail frame that's up to get down. Its Alpha Platinum Aluminum chassis delivers progressive hardtail trail geometry that's 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.

This bike has a maximum total weight limit (combined weight of bicycle, rider, and cargo) of 300 pounds (136 kg).
