The new bike turned up last week. It's brilliant. On the road, it feels like a road bike. Off road, it feels like a rigid 29er, only with drops. Having discs is an absolute revelation on a cross bike - the brakes allow you to really hammer the trails and know you can actually stop/slow down. The handling is very mountain bike - really chuckabke and nimble. Just back from a loop round the Surrey Hills taking in a couple of the drier trails (Secret Santa, Supernova and Barry's) then heading home. Fantastic for an after-work ride.
If you are interested the spec is Ultegra gears, CX-70 chainset, 105 STI levers, USE carbon finishing kit, Hope/Stans Crest wheels, Racing Ralph 700x35 tyres. I am also running road pedals (105) as I hate the rattly feeling of mtb pedals on a road bike, and seeing as I spend most of the ride on the road and don't race cross they are fine.
You all need one.
