Orange Mountain Bikes - RX9 Spec Sheet

From the 2015 Archive


The Thing from Orange Mountain Bikes on Vimeo.

Built with the Orange Bikes' ride philosophy firmly at the top of the list, the relaxed (for CX/Road rules of thumb) geometry hits the right balance to give the RX9 the ability to ride just about any terrain this side of rocks and boulders. We built it to be a workhorse and to put a firm tick in the box next to 'Fun'.

The RX9 is your go-anywhere, black top to dirt track mile muncher. Whether you’re commuting to work, exploring the local countryside or taking a cruise along the coast, the RX9 will smooth out the miles. The double-butted alloy frame has been honed to provide a frame that is stiff enough to put your power to the black stuff, while being comfy enough to take the edge off bridleway chatter.

This is the bike for anything, with mounts for mudguards or racks, proven Shimano components, dependable disc brakes and a comfortable alloy or carbon fork ensure sharp handling and confidence in all conditions.

Why the RX9?

With a Shimano Sora drivetrain, Avid BB5 disc brakes and Easton finishing kit, the RX9 might be our entry level drop bar bike but it feels anything but.

Want to up the spec? You’ll be after the RX9 S. Like the idea of skinny tyres but not keen on drop bars? Take a look at the Express-O.
