You have places to go, people to see, and fitness goals to achieve. We get it—life moves pretty fast, so it's a good thing we made Sirrus to help you with all of it.
Wherever you're heading, Sirrus will take you there. Sirrus features a super light aluminum alloy and carbon fiber construction, as well as reliable Shimano components that are built to withstand years of daily abuse on the world's pavement. Powerful hydraulic disc brakes provide reliable stopping power in any condition, and comfortable, ergonomically designed Body Geometry touchpoints are there to take the sting out of longer rides. So, as you push yourself to reach your goals, you'll feel more connected to your bike and know that you have the perfect partner with Sirrus.
Features:
- Carbon FACT 9r fork delivers comfort and saves nearly 3 pounds (1.2kg) over Sirrus 2.0 model.
- Thru-axle hub connection for positive wheel alignment and no-rub disc brakes.
- Wide-range 2x10 Shimano components for intuitive and precise shifting.
