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.

Real Fit. Real Fast.

The all-new Men's and Women's Sirrus is out to give you the perfect blend of everyday efficiency and the performance you need to hit your fitness goals at speed. It's also the lightest Sirrus we've ever made, dipping as low as 19.8lbs for the Pro Carbon model, and it features brand new Body Geometry grips, bar ends, and saddles that are the result of intensive study and engineering. Let's take a look at some of the new features that are going to give you an ear to ear grin.

The Future is Shocking

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.

Modern Components

With flat-mount disc brakes, front and rear thru-axles, cruise/climb gearing, and our coveted CG-R seatpost, the Sirrus brings fitness bikes into the future. Seriously, we've thought of everything for your ride. Want the most sophisticated, thought-out integrated grips, bar ends, shifters, and brake levers for the cleanest possible cable routing? You got it. Need ample room for up to a 35mm tire? No problem. Rear rack compatibility to haul your gear. It's there. And we even included corrosion-resistant bolts, stainless steel cables, compatibility with Plug & Play fenders, and some of our most comfortable saddles.

Data Driven Geometry

All of the new Sirrus frames, both carbon and aluminum, come with a redesigned geometry based on thousands of men’s and women’s Retül data points. From this collection of data, we made the Sirrus with an easy, comfortable reach to the bars, and a size range that’s linear between sizes. So, no matter if you’re a Small or an X-Large, you’re sure to have the perfect fit. And when you pair this with Body Geometry touch points, you’ll be spinning all day in total comfort.
