Hey guys you all have SUCH a great forum. I've been learning so much.

I am runner mostly and have decided to take up tris. I have been training for about a month on a borrowed Giant OCR1W road bike (properly sized and fitted). I am really loving the speed and challenge of cycling and can see myself really getting into this. So now that its time to buy a bike I need advice. I was thinking of spending about $1200+ but could be convinced to spend more. I have been into shops to ride around on a few Specialized and Treks and have been using the Giant. I had a friend send me this link though and thought it sounded like a great deal

Its a 48 cm (my size) titanium tachyon from the late 90s. Its only been used 500 miles and the components appear to have been well cared for. Oh, and the lady only wants $1000.

My main concern is that this is a tri bike and I don't know how that would influence my ability to enjoy the longer group rides that I could see myself getting into. Should I be concerned about the 650 wheels?

Thanks for any advice! Also, I'd love leads on other used but fabulous bikes if anyone has any suggestions.
