Accelerates quickly, handles confidently
Traffic jams, queues and constant stop start. Instead, jump on the Specialized Sirrus and beat the traffic. 700c wheels, aluminum or carbon frames, disc brakes or v-brakes – the choice is endless. The ideal bike to improve your fitness, the Sirrus accelerates quickly, handles confidently and a host of Body Geometry components ensures that it is comfortable on the longest of weekend rides.
The top of three models in the range feature a FACT 9r carbon fibre frame. Stiffer, lighter and more comfortable than their aluminum siblings, the carbon fibre versions all feature more powerful hydraulic disc brakes to ensure optimal braking performance in the worst weather. The Sirrus Expert Carbon Disc also features a new 11 speed Shimano 105 drivechain, partnered with a FSA Gossamer chainset. A carbon fibre seatpost improves the rear end compliancy whilst and alloy bar and stem combination maintains the quick, responsive steering. The Comp Carbon Disc and Elite Carbon Disc use 10 speed Shimano Tiagra and 9 speed Shimano Sora respectively.
Another unique feature that the carbon versions have over the aluminum alternatives is the addition of the Zertz viscoelastic dampers, which filter vibrations from the road, ensuring a silky smooth ride over the roughest roads.
That being said, the aluminum versions of the Sirrus are one of the most versatile and robust commuting/fitness bikes around. The Elite Disc and the Comp Disc use the latest butted E5 aluminum tubing along with a FACT carbon fibre fork to ensure a comfortable ride. Specialized’s proprietary A1 aluminum is used on the two Sport models, along with the option of either conventional v-brakes or disc brakes.
