Introducing Gary Young's signature Wavelength frame. With a longer rear end and top-tube options, this frame is designed for riders who love to go fast and want a more stable ride for trails and transitions. FEATURES Gary Young Signature Geometry 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.
