    About

    Since 1974, we've had one goal: Innovate and inspire to improve riders' lives.

    Innovation

    Innovate or Die. Three words behind every design decision we make.

    Stories

    Bikes are part of a greater culture with tremendous stories. This is where you'll find them.

    Sustainability

    We recognize that the decisions we make have social and environmental impacts and that we are responsible for minimizing them.

    Retül

    Helping riders make data-driven decisions to improve the ride.

    Outride

    The Specialized Foundation uses cycling as a tool for children to achieve academic, health, and social success.

    Sirrus X is your ticket to riding more, and to places you never imagined possible. It’s a comfortable, capable, “let’s do stuff” kind of bike that will inspire you to ride more than you ever have before. With bigger, confidence inspiring tires, a slightly more upright riding position, a super intuitive one-by drivetrain, and plenty of mounts for racks and fenders —it’s more than just a solid partner on pavement. Sirrus X is a dialed option when it’s time to hit some gravel. We’ve also equipped every Sirrus X with next-level comfort from our scientifically tested and ergonomically engineered Shared Platform Body Geometry saddle, handgrips, and pedals. We equipped Sirrus X 4.0 with the revolutionary Future Shock to take the sting out of bumps and potholes. Here’s to your life on two wheels.
    • Future Shock 1.5 delivers 20mm of compliance to give maximum comfort and control over the rough stuff.
    • Added Carbon Fork and an A1 SL alloy frame delivers a build 1.6lb (.8kg) lighter than the 3.0 model–no heavy hybrid featuring a mountain style suspension fork comes close.
    • Wide-range 1x11 Shimano Deore shifting delivers precise shifting for the long haul.
    Sirrus X是您开拓广阔骑行空间，享受更多骑行乐趣的门票。它舒适、通过性强，并且鼓励您和它一起探索，骑行更多。更宽的轮胎增添信心，直立的坐姿和符合直觉的单盘传动，以及丰富的安装点以兼容货架和挡泥板。它不仅是铺装道路的好伙伴。Sirrus X在需要进入碎石路面时也已经准备充分。我们给Sirrus X配置了符合人体工程学设计，男女通用的Body Geometry坐垫、把套和脚踏，带来更好的舒适性。在Sirrus X 4.0上还带有Future Shock避震，以缓解凸起和坑洞带来的颠簸，这就是你两轮生活的伙伴。
    • Future Shock 1.5提供20mm行程，在颠簸路面上带来更好的舒适性和可控性
    • 碳纤维前叉和A1 SL铝合金车架让整车比3.0型号轻了约800g，重型跨界车配置山地车那样的避震前叉很难达到这个重量
    • 齿比宽广的1x11 Shimano Deore传动提供精准的变速且经久耐用
