I test rode the Cannondale. It certainly looks nice and I generally realy like Dales. I don’t know what it weighs but it felt heavier and a bit more “dead” than I expected and some of the components seemed a bit cheap. I’d go for an on one or a 2nd hand Swift if I was you.
In the end, I saved up a bit more and built up a Swift. It’s lovely.
As epicyclo said, I think getting some nice light wheels is pretty important on a 29er – makes a big difference to the ride.
