Mark Burnett’s signature frame is designed around a geometry that matches his technical East Coast riding style. It features short chain stays, a taller bottom bracket, a longer head tube, and smaller hollow dropouts with integrated chain tensioners.
100% 4130 Chromoly Frame (Post-Weld Heat-Treated) MotoRoss style, double-butted, top and down tubes with proven internal gusseting. Built without U-brake hardware and Gyro tab holes.
Integrated seat clamp.
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 tube 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. The 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 place as well as simplify wheel removal.
