Roscoe 8 Gen 4

What is different compared to previous versions?

• Roscoe Gen 4 has updated geometry for improved standover clearance and longer dropper post insertion. Instead of a 130mm post being fully buried in the seat tube on a medium, most medium riders can now run a 170mm dropper post.
• A new, steeper seat tube angle keeps handling balanced and pedaling efficient.
• Roscoe’s new frame comes in five sizes instead of six. Because of the increased standover clearance, the reduced size run doesn’t limit rider fit, providing a bike for the same range of rider heights.
• A new bolt-on downtube guard improves durability and frame protection.
• Additional mounts are available under the top tube to store a tube, tool, or another bottle cage on larger sizes (when a frame bag is not installed).
• New zero-stack press-in headset cups allow for aftermarket angle-adjust compatibility
• All frame sizes feature one set of water bottle mounts on the downtube. To allow for improved dropper post insertion, there are no water bottle mounts on the seat tube.
• Increased fork travel to 150mm
