With a Dura Ace lockring, that rear Miche hub is useless. Might as well be riding without one. And with those heavy ass rims, I'd rather just not have the wheels.
I'd give about £80 for the frame, £20 for the bars, £35 for the stem if it was longer and about£25 for the seatpost. Are the cranks the newer Miche that the chainring bolts thread straight into the crank? If so, I'd give a fiver for 'em.

So, adding it up... about £165 or $300

*edit, OOPS... Just re-read that the hubs are Dura Ace. That makes the wheels much, much better. Sooo... about $425.
