Word on the street is that fitness bikes tend to sit on the side of value over performance, well we'd like to reply with our Sirrus Expert Carbon X1. This bike sets out to prove that a fitness bike can combine efficiency with performance so you'll be reaching your goals, and at considerable speed. We've given this bike a high quality FACT 9r carbon construction that's light and ultimately responsive. You can also expect precise-shifting, frustration free, with the SRAM X1 drivetrain, plus the comfort of our engineered Body Geometry components. If you're looking to push yourself to new heights, feel connected with your bike and enter a world of new health and wellbeing, check this bike out.

With a FACT 9r carbon fibre construction, the frame has been designed with our Fitness Geometry, resulting in a lightweight, durable and totally comfortable platform. We believe a comfortable rider rides harder and for longer. We've also equipped the Sirrus Expert Carbon X1 with a lightweight FACT carbon fibre fork that, with its Zertz inserts, absorbs road vibration to make for a smooth and responsive ride regardless the conditions.

With this type of performance you need stopping power to suit, with the Shimano Deore hydraulic disc brakes you'll be stopping immediately - be it wet, snow, sandy or whatever the road slings your way.

The Sirrus Expert Carbon X1 - it's here to turns heads and change opinions in fitness cycling.
