Specialized Sirrus 2011 - Road Bike

Fun can be serious work. The reasons you might ride will vary: could be an easy Saturday ride with friends, a 6:00 a.m. commute to work, even a 600-mile, week-long charity ride. Regardless of why you're throwing a leg over a bike, you need one capable, comfortable machine that covers all the bases with efficiency and ease. The Sirrus is just that: a lightweight, head's-up road ride that helps you beat car-trapped commuters home with a measure of safety on the weekdays, yet is still light and efficient enough for a long spin on the weekend

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.

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