Orange Mountain Bikes - Clockwork 120 Spec Sheet

From the 2015 Archive


With its 27.5inch wheels, 120mm of travel and singletrack honed geometry, the Clockwork 120 is the choice for those looking for a potent blend of quick handling and rapid acceleration.

We’ve used our geometry knowledge, gained from over a quarter of a century of frame design, to make this a bike that comes alive when fired down twisty trails but is just as happy when you want to take it easy and enjoy the view.

The Clockwork 120’s lightweight aluminium frame is packed full of features; custom butting and shaped tubes provide the right balance of feedback and comfort. A chainstay mounted disc brake mount combined with internal brake, gear and dropper post routing make for a sleek profile.

A light but stiff frame coupled with 27.5inch wheels makes for a quick and engaging ride, whether that’s blasting round the local woods or getting out into the wilds.
