Sunday Darkwave Frame

100% 4130 chromoly frame - Broc Raiford signature geometry. - Removable U-brake hardware and Gyro tabs - Integrated seat clamp - Wave Down Tube: Down tube dents are common with the competitor's frames and they significantly weaken the front end of your bike. The double-butted, 1.45" diameter down-tube feature Sunday's proven Wave shaping to fight denting against contact made from a rail, ledge, coping and whatever else happens to get thrown at it. - 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 junction 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. 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.
