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.

Simplicity rules on the Excelsior and it’s built without u-brake hardware and Gyro tab holes. The frame’s front triangle makes use of traditional round MotoRoss style top and down tubes with proven internal gusseting.
