Frankly, the price looks good. But a few things that I'm not able to understand:
1. The Sirrus is a flat bar bike - but the bars in the picture look to be riser bars. Non-stock?
2. Tires are definitely not stock, but that isn't necessarily a bad thing
3. Mismatched wheels
I don't think I can comment much more on the price based on that one photo - for all I know, Specialized may have had a model that had all the things I spotted (except the mismatched wheels - am pretty sure that wouldn't happen). I'm not much of an expert anyway - do you have a knowledgeable friend who can accompany you when you go to check out the bike?
