If you can get it for a good deal, it looks like a nice lightweight bike with carbon stays and a carbon fork. However, for nearly the same retail price, you can get a scott sub 20, which gives you better components and imo, a badass looking frame (because i have one).
The sirrus in white does look awfully purty but you get a lot of bottom of the line 8 speed stuff whereas with something like the scott, you get midrange 9-speed stuff.
