Sunday Street Sweeper BMX Frame 21"

Features

• 100% 4130 Chromoly Frame
• Nightshift style, double-butted, top and down tubes with proven internal gusseting.
• Integrated seat clamp
• Butted Seat Tube & Miter Cut Top Tube:
  A miter-cut top tube creates a precise joint with the seat stays during welding. This increases the strength substantially over frames that use a “sandwiched” top tube at this critical junction.
• Tapered Chain & Seat Stays:
  Both chain and seat stays taper to provide a refined and clean look to the frame while still providing strength. They are both angled on the inside for improved chain clearance and weight savings.
• 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 position and to simplify wheel removal.
• Removable Brake Hardware:
  Proven, removable, brake mounts and cable guides/stops work flawlessly when installed and allow for a sleek overall look when they’re not.
