The retail on those frames is only around 2K.
So basically you're paying $2K for a used frame/forks and a bunch of what appear to be junk parts. As one of the other guys said it's not race legal in it's current setup, you need 2 wheels the same diameter.
I've seen those old HED discs going on ebay for a few hundred.
If it was me, I'd buy spend a few extra bucks by buying the frame/forks then putting a decent build on it.
I'm personally racing on one of those frames at the moment. It's not bad.
My build is:
Miche rear disk (Zipp 900)
TWE front carbon 50mm or X-treme 80mm front carbon
Easton EC90 track bars
I got mates rates on quite a bit of the above, but my total build cost was only about $3,500 (AU).
