100% 4130 Chromoly Frame
Nightshift style, double-butted, top and down tubes with proven internal gusseting.
Removable U-brake hardware and Gyro tabs

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.
Tapered Chain & Seat Stays:
Both chain and seat stays taper to provide a refined and clean look to the frame while still providing strength. The are both angled on the inside for improved chain clearance and weight savings.

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: 75ΒΊ - 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: 71Β°

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 πŸ‘ 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.
