Orange Mountain Bikes - ST4 Diva Pro Spec Sheet

From the 2012 Archive


The ST4 created a category of its own as a confidence inspiring XC trail bike. Easy to pedal with fantastic handling on the downs – it quickly became a classic, particularly with female riders. This year we’re capitalising on what we’ve learnt by making an ST4 Diva specific to the female physique. A shortened version to better distribute weight and create a more comfortable bike with increased front-end traction.

Using a low leverage ratio, the ST4 is supple at the start of the stroke to provide small bump sensitivity, it then ramps creating a deeper feel to the travel beyond the pedal platform. Air forks help balance the front to create a lively short travel XC bike which tracks terrain with stability only matched on bigger bikes. Female specific spec choices compliment frame design to create a rounded package for the riding you’ve always wanted to do.

The ST4 redefines the rules of XC riding, the ST4 Diva just adds the female touch.

Why the ST4 Diva Pro?

The Diva range expands to include a more XC focused female specific package. Shorter travel than a Five, but comfier than a hardtail, the ST4 is the perfect compromise between pedaling efficiency, comfort and technical ability.

For a bike with a little more suspension travel, take a look at the Five Diva. If a hardtail is sufficient for your kind of riding, look at the standard Diva.
