100% 4130 chromoly frame
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.
