The Sirrus has long been a fan favorite, and this year, we're taking it to a whole new level, for both women and men. That's because we gave it a whole new geometry, an even lighter frame, and yes, our coveted Future Shock that's found on some of our highest performance road bikes.
Maybe you’ve heard about this Future Shock, maybe you haven't. We developed it for our Ruby and Roubaix, and we even integrated it into our Diverge, albeit with a more rugged spring. And now, we're applying its smooth as silk front end damping to the Sirrus—an absolute first for this class of bike.
But what is it really? Essentially, it's a piston in the head tube with 20mm of travel (it comes with a 40lb spring installed and 12lb & 25lb springs in the box). Our aim was to completely change how vertical compliance is achieved. And without giving a physics lecture, we found that the Future Shock improves smoothness, speed, and comfort in one fell swoop.
