Orange Mountain Bikes - ST4 S Spec Sheet
From the 2011 Archive
The ST4 may take the name of the old, but it’s all new, a veritable conglomerate of design made to continue our own inimitable niche. The original brought responsive trail handling to a bike designed for regular XC. A low slung trail missile which pedaled efficiently and descended with a rapidity that astounded the most fervent critic. A bike that doesn’t fit a category, but creates one.
Built for all-day missions, the ST4 uses a low leverage ratio to produce 110mm of buttery smooth travel. Rather than use a shorter 165 mm shock the ST4 takes a lesson from the blood, running a 190mm custom tuned Fox RP23 shock to give 100mm perfectly controlled progressive travel driven through single pivot linkage actuated design. The geometry that made the original a classic, but updated to markedly stiffen the chassis laterally and incorporate linkage development from the Strange department.
If you want to redefine the rules of XC, the ST4 starts afresh. It might not fit the existing industry tags, but it’s built for the way most of us ride. Up, down and along, the ST4 is the remedy to your bike pondering woes. Just get on and ride, the ST4 does the rest.
Why the ST4 S?
Wanting a spec without all the bells and whistles? The ST4 S provides a robust package ready to hit the trails, with options available if you want to make key upgrades on what matters to you. If you want a little more, the ST4 Pro is the next in the range.
