Butted Seat Tube & Miter Cut Top Tube: |
The seat tube is where all three triangles of the frame meet and it is crucial to keep this tube strong. |

Frame Geometry
A: Top Tube Length: 20.75″ or 21″ – Learn what size is right for you here.
This is a pretty long top tube. Best for taller riders 5’6″ and up.
B: Chain Stay Length: 13.25” to 13.5″ – Learn About Chain Stays Here
This is a long chain stay. Longer Chain-stays give you more control when doing manuals and bunny hops.
C: Head Tube Angle: 75º – Learn About Head Tube Angles Here
Steep head tube angles make the bike “snappy” meaning more responsive to fast turns.
A less steep head tube gives you more control.
D: Seat Tube Angle: 71°
E: Bottom Bracket Height: 11.8″
F: Stand over height: 9″
This is a tall standover. A tall standover gives you more control with barspins and t-bogs.
Conclusion
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.
