If you want to receive the bicycle of your dreams ready for use, remember to add the bike assembly (see link).
You have places to visit, people to meet and fitness goals to hit. We get it, life is busy, that's why it's a good thing we created Sirrus to help you with it all. Wherever you're headed, the Sirrus will get you there. The light alloy frame is equipped with reliable Shimano components to guarantee many years of riding on asphalt. The hydraulic disc brakes are powerful and reliable in any condition, and thanks to the Body Geometry contact points it will not be a problem to spend long hours in the saddle. So when you push yourself beyond your limits to achieve your goals, you'll feel very 'connected' to the bike, and you'll know you've found your perfect fitness partner.
- A1 light alloy frame with space to mount tires with a section of up to 42c, internal cable routing. Lowered tube to be able to get off or on the bike easily.
- Intuitive Shimano RapidFire 2x8 controls.
- Hydraulic disc brakes for maximum safety and control.
- Racktime luggage rack to quickly attach the practical bags, and Drytech mudguards to protect you from water and dirt.
- Very bright front and rear lights, powered by the Shimano Dynamo Hub.
