Specialized Sirrus Expert 2010 - Road Bike

The speed and performance of a road bike but with the comfort and control of a flat handlebar and more relaxed riding position make the Sirrus Comp the ideal fast commuter/fitness bike.

Specialized's excellent components including their awesome saddle, grips and tyres round off the Sirrus Expert and make it as nice to ride as it is to look at!

  What is a Road Bike?
  Referred to as road racing bikes, the clue is in the title here. These bikes concentrate on being light weight and reducing drag to increase speed. Thanks to their drop handlebars they have a stretched out feel, again for aerodynamics. So efficiency is the name of this game, definitely not comfort. For more information on road bikes see our Road Bikes Buying Guide.

Occasionally, without notice, manufacturers change product design and/or specifications.
