Marin Four Corners, XL (2021) Gloss Green/Tan

SBC ID | MFG SKU - 210000067608 | 732425005

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.

Why you'll love it: 

The butted 4130 CrMo steel frame and fork are designed to handle fully loaded touring, with up to six bottle mounts, rack and fender eyelets, lowrider fork mounts, generous tire clearance and disc brakes to bring it all to a stop. Four Corners geometry is based on biometric fit data, and we offer five different frame sizes with size proportionate 650B or 700C wheels to properly fit riders between 4’11” – 6’4”. The bars are set high for all-day comfort and heads-up visibility in traffic, with mountain steering geometry capable of taking you down whatever path your destination requires.

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.

Fork leg bottle or accessory cage mounts on the base Four Corners, along with traditional front triangle bottle mounts (three on sizes M-XL, two on XS-S) provide up to six bottle cage mounts total.

Disc brakes provide smooth, controlled stopping in all conditions with minimal maintenance.
