Online Sirrus 1 order - excellent experience

I ordered a Sirrus 1 bicycle and had it shipped to a local bike shop to have it assembled for me. The bike came in just about a week, the bike shop turned it around in less than a day and I love the bike, it's just what I needed. Great work to Specialized and their online purchase process (network).

A very fast bike for

A very fast bike for the price! I was looking for a fast bike at a lower cost while staying with my uncle for 3 months and picked this up. Probably the fastest bike you can buy at this price. It was a little smaller than I expected (ordered size M I’m 5’7) but still fits pretty well.
