Sunday Wavelength Frame Matt Black

- gary young signature geometry - 100% 4130 crmo - removable u-brake hardware and gyro tabs - wave down tube: - down tube dents can significantly weaken the front end of your bike. The wavelength's double-butted 1.45 diameter down-tube features sunday's proven wave shaping to help fight against denting from rails ledges coping and whatever else happens to get thrown at it. - 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.
