About This Product: Sunday Nightshift BMX Frame-Copper Drop

The Sunday Nightshift BMX Frame-Copper Drop is a 21.25” top tube frame, all 4130 chromoly, and heat-treated using Odyssey's 41 Thermal treatment. This creates one of the strongest frames around. So strong that Sunday offers a lifetime warranty against bending, cracking, and breaking. Prior to being painted it is coated with Black Magic anti-corrosive. Naturally the brake hardware is removeable. The super strong 8mm hollow dropouts have internal chain tensioners for precision tuning.

FEATURES

  • 41 Thermal Processed (Lifetime Warranty): Sunday is the only company to use Odyssey's proven and trusted 41 Thermal heat treating. This formula has been refined and improved since the late 90's. The proven 41 Thermal process allows products to be lightweight AND strong. It is also backed by a legendary lifetime warranty against bending, cracking, and breaking.
  • 100% 4130 Chromoly Frame
  • Double-butted top and down tubes with proven internal gusseting.
  • Post Weld Machining: The Mid BB and Headtube is machined to its absolute minimum without sacrificing strength or durability. The machining happens after welding for a precision bearing fit.
  • Hollow Dropouts with Chain Tensioners: Hollow 8mm wide dropouts are as light as a solid 5mm dropout, but over twice as strong. There is a small internal chain tensioner to hold the wheel in place as well as simplify wheel removal.
  • Removable Brake Hardware: Refined, removable brake mounts and cable channel improvements that provides benefits with or without a brake setup.
  • Rust Proof Coating: All Sunday frames are rust-proofed with "Black Magic" coating before the final finish is applied. It is lightweight and the best anti-corrosion processing that's offered today.
