Thanks. Don't know much about K2. Little research says they got bought out some time ago. I knew it was an older bike when I got it but aside from some scrapes here and there, it's in really good condition overall. Like I said earlier, main reason I bought it was for the 105 hardware. CF front fork and rear seat stays(?) on an aluminum frame make it pretty light and comfortable. I do need to change that chain ring but even with it, the bike rides fine. I'm really happy with it. Even putting new bar tape and pedals on it I'm still in for under $300. I don't think that's too bad at all.
Now I need to sell off a couple others that just gather dust.
