Specialized Sirrus Expert Carbon Disc Hybrid Bike 2019
With a carbon frame and fork, integrated suspension system and Body Geometry components, the Specialized Sirrus Expert Carbon Disc Hybrid Bike is more than just another commuter bike. It is a bike which will encourage the long way home and weekend use, just for the simple pleasure that riding brings.
The 11-speed Shimano gears offer a wide range of ratios to help up and down the hills, and the TRP Flow Set Control hydraulic disc brakes will keep things under control with just a light touch on the lever even in the wet. The 30mm wide Specialized Espoir Sport Reflect tyres provide reliable grip, comfort and low rolling resistance, and have reflective strips around them to increase side visibility.
Specialized are particularly proud of the Future Shock Suspension system that they have integrated into the headtube. This device gives up to 20mm of sprung travel without the weight, cost or stiction of more traditional fork based suspension. This system is purpose-built and designed for road use and will greatly increase comfort without sacrificing any speed; in fact, Specialized claim quite the opposite as the reduction in fatigue actually increases speed.
The frame and forks come ready prepared to mount Specialized’s Plug + Play Fender Set; mudguards which will quickly and easily attach to this frame and fork (sold separately).
