Best cyclocross bike under £1000 and other CX chat

Things have become much more lax with c2w recently- I've been offered a groupset on c2w- they said they'd just put "Shimano Ultegra Di2 bike" on the form.

So I'm sure you could get a rolling chassis, or just some wheels.

Would be great if PX let you have Athena + a dirty disco frameset for £1k.

The groupset is 50/34 to 12-27 too.

Having said that. What hubs take a disc rotor, and a campag cassette?
