Orange Bikes
ST4 S
You’re looking at the sleekest, smoothest, corner-railingest trail bike out there. With 100mm of supple, controllable traction, a low centre of gravity and a tight back end for unrivalled climbing performance, the ST4 is the bike you wish you were fast enough for.
The Rokr linkage allows us to run the 50mm stroke shock at a low-ratio of 2:1 giving precise control over every millimetre of shock’s stroke. Running a ‘long’ stroke shock on a ‘short’ travel bike effectively enables us to use a larger volume air spring at a lower pressure. This provides more supple feel at the back wheel and increases traction by maximising the rear tyre contact on the trail.
Did we mention that this is the shortest, snappiest suspension bike we’ve ever produced? It’s no slouch when it comes to the bigger hits either – in fact the ST4 is the mountain bike for riders who’ve grown with the sport and can now ride further, faster, higher and steeper than ever before. Congratulations, you’ve just met your match.
