2013 Rocky Mountain Altitude – same name, totally different bike

‘New’ bike, same name. That’ll just mean a few tweaks then – a degree off the head angle, a tweaked leverage rate. Not the 2013 Rocky Mountain Altitude – it’s got an all-new frame, suspension setup and wheel size, plus the top-end models are now carbon fibre. Rocky reckon it’s “the total trail bike package”. It’s certainly easier on the eye.

2 Frame material

The 2012 bike had an aluminium frame. Now there’s a choice of carbon (Altitude 790 MSL), carbon front/alloy rear (770 MSL) or alloy (730, 750).

3 Adjustability

The new RIDE-9 system allows you to adjust head angle (66.6°-68.3°), BB height (+/-10mm) and suspension rate via a pair of rotating chips at the upper shock mount

4 Pivots

The bike uses Angular Bushing Concept pivots instead of cartridge bearings. These are said to be lighter, stiffer and need less maintenance

5 Travel

The 2013 Altitude offers 150mm of travel, up from 140mm, via a reconfigured version of Rocky’s four-bar SmoothLink design
