Cube's 29ers have a different geometry to other 29ers, hence riders feeling at home on them straight away
They use the same BB height as a 26er & I think they also use the same wheelbase as a 26er (trying to remember exactly what the rep told me 6 months ago lol)
They have a patent (pending) on the front mech mount too IIRC
Excellent value bikes (my honest opinion, even though I do sell them!)
I would say that my 120mm travel Sting is as capable as the 140mm Orange 5 that I sold to get the money for it & it's a good 2 or 3lb lighter!
Cube sold out of the 29ers so fast last year they didn't know what had hit them!
This year most of the range is available in 26 or 29" wheels, and there's also a 650b Stereo
