Model Description

The all new Orange Four is designed to fill in the gap below the highly evolved Orange Five, with a snappy, playful 120mm of rear travel and super short chainstays for superior climbing ability. The Four retains the simple single pivot suspension system Orange have become famous for over the years, but with a modern Boost 148 rear axle spacing, and super short chainstays for a playful nature. Other modern geometry features a longer top tube and slacker head angle for a stable feel on descents. Built with the entry level Pro kit, you get Fox Performance suspension front and rear, and Shimano XT/SLX 1x11 drivetrain which both provide a fantastic base to build on and compliment the new short travel trail bike perfectly.
