Hi treadtread,
Thank you for the response. I read it wrong, it's not Sirrus 4, it's Sirrus 4 short rider - I'm not hip enough for abbreviation obviously.
The ad is sketchy. After being asked those questions, the owner only replied with "na" Here's the ad

If the fork is not carbon and there's no dent, is it still a good deal? Or maybe it's a stolen bike?
