This is a long chain stay. Longer Chain-stays give you more control when doing manuals and bunny hops.

The Discovery frame is made to last. Sunday kept simplicity in mind by using a clean design. I like the built-in chain tensioner and the removable brake hardware. Oh, and the 🍑 color is pretty sick too. If you are a rider that is taller than 5'6" looking for a strong frame upgrade this is for you. The Discovery is geared for burly street riding due to the big geometry and heavyweight.
