Ergonomic Fitness/Commute 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.
