Specialized (USA) – "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", explained Specialized.

The Future Is Shocking:
Specialized developed Future Shock for their Ruby and Roubaix, and they even integrated it into the Diverge, albeit with a more rugged spring. Future Shock it is a piston in the head tube with 20mm of travel (it comes with a 40lb spring installed and 12lb & 25lb springs in the box). According to Specialized 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", they added..

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", concluded Specialized.
