The Four Corners is built for the adventure rider looking to explore deep off of the beaten path, sleep outdoors, and be ready for whatever pavement, dirt road, or light singletrack is around the next corner. The heads-up bar position and generous braze-ons that make it possible to live on the bike for days at a time are equally at home on the daily commute. FIVE FRAME SIZES The Four Corners is available in five frame sizes to fit riders 4'11 to 6'4" without compromise. For proper fit and bike handling sizes XS and S use 650B wheels, sizes M, L, and XL use 700c. BOTTLE / GEAR MOUNTS Traditional front triangle bottle mounts (three on sizes M-XL, two on XS-S) provide up to three bottle cage mounts total, with full fender and rack mounts throughout for expanded carrying capacity. DISC BRAKES Disc brakes provide smooth, controlled stopping in all conditions with minimal maintenance.
