I brought one about a month ago.
Its suprising how well it rides, seems fine to me on the steeper stuff.
I am running 140mm Revs on mine.
Its the bike i use 99% of the time now, I also have a Nicolai Ion 16 650b and this is rarely used.
One thing i did change was the Fox CTD Evo that came on the frame, Horrible shock,Either set up so it works on small stuff and it then bottoms out all the time, or set up to not bottom out made it not work on small stuff.Replaced with a Monarch RT3 and has transformed it.Also adding some Bottomless tokens to my Revs helped.
