Description
Utilising a strong, stiff and lightweight aluminium frameset, the Specialized Sirrus X 3.0 Disc Hybrid Bike promotes a lively performance during town errands or weekend adventures across countryside gravel paths. A slightly more upright riding position combines with the robust wheels, high volume tyres and ergonomic saddle to ensure comfort is high across rougher terrain, while mounts for luggage racks and mudguards make riding longer distances or in bad weather more manageable.
A wide-ranging 1x9-speed gear configuration shifts smoothly and offers a vast range of sprockets so that almost any topography can be tackled. Hydraulic disc brakes complete the build, operating with aplomb even in the teeming rain.
