Need a bike that's affordable, easy and fast to get around on, that's hassle-free and needs low maintenance and is compatible with racks and fenders mounts so you can carry bags to and fro on your journey ... Look no further. The Sirrus models are made for commuting on different surfaces and different speeds so no matter where you need to get you can rely on it to get you there. The Sirrus is a great option for those looking to purchase a bike through the cycle2work scheme and with hydraulic disc brakes they provide reliable, safety the whole year through. This model also features Specialized's lightweight premium A1 aluminium frame, which is backed by their lifetime frame warranty that ensures performance forever. Finally, Shimano's Tiagra 10-speed groupset provides smooth shifting that's reliable all year round and TRP's hydraulic disc brakes prevent uneven braking patterns when the weather starts to get worse and the roads get wet.
Working with Specialized's Body Geometry team, they designed a frame that strikes the optimal balance between comfort and efficiency. The A1 SL Premium aluminium construction pairs weight savings with rugged durability, while the rack, fender, and disc mounts give you an incredibly versatile package.
