2017 Orange Four RS 27.5″ Mountain Bike


Less is more. The Orange Four RS 27.5 is a short travel full sus trail MTB that combines progressive geometry with just enough suspension travel to offer lightning fast mountain bike performance over the whole trail.

Faster and lighter than big hitting trail bikes yet more capable than an XC steed, the Orange Four is the ultimate short travel trail bike. Progressive geometry offers confident handling on every trail. The rear swing arm is compact which allows for short chainstays for improved climbing ability and manoeuvrability. The long top tube is combined with a short stem and slack head angle which keeps the wheel base long for stability at speed and fast, direct handling characteristics.

The aircraft grade 6061 aluminium frame features CNC machined detailing which keeps the frame weight low while keeping things stiff and strong. The split design rear swing arm also shaves off a few grams and, combined with the 12×148 Boost hub spacing, adds rear end stiffness. All these marginal gains, or rather losses, add up to an extremely lightweight and capable frame.

The 120mm of rear wheel travel is controlled with a compact RockShox Monarch RT3 shock that offers efficient performance on the ups as well as the downs. The Four is optimized for a 130mm travel fork which allows you to run slightly more front end sag for that plush ride feel. The RockShox Pike RCT3 fork offers composed performance on even the very roughest of trails. Of course, being an Orange you also get the opportunity to upgrade the shock and fork as well as other components.

The SRAM 1×11 speed drivetrain offers assured shifting performance with a wide range of gears for riding every trail section while the SRAM Guide R disc brakes give you confident stopping power. Renthal Fatbar handlebars and KS Lev Integra dropper post round off the dialled spec list on this super-fast trail bike.

The Orange Four RS sports less travel but offers more speed.
