Sunday Bikes (United States) - Sunday's new Discovery team frame features short chainstays, a tall bottom bracket, a long head tube and small hollow dropouts with integrated chain tensioners.

Simplicity rules on the Discovery. The frame’s front triangle makes use of traditional round Nightshift style top and down tubes with proven internal gusseting. Removable brake hardware and Gyro compatible as well.
