clearly you can ride as the rest of the post says, but if you are not a stick insect xc rider then be warned that Cannondales do/did have a very nasty habit of breaking. They simply make the frames too thin. For a similar ride have a look at the titanium GT/Kona or an ali Merlin.

Avid brakes rock, no questions. Got most of the mens XC on Swedish TV today,  really good coverage. Well done to the 22 year old Brit who came in 6th, top performance! 

Edit: it was Liam Killeen and he came 5th!
