Yes I have one, had it since January, there was only a very limited run apparently. I had the last but one medium to be 'allocated', but they are only a small company. My new bike thread with some pictures.
What's it like... Dunno, only 'just' got dry trails locally, so am just getting to learn to ride it fast
Though it happily dealt with the crap this year has thrown at us until now, which honestly was my main reason to buy it.
I've used it in the mid 1146mm chain stay length until lately, in mainly crap/gloppy/snow conditions. Felt very stable, happy to do any long haul XC stuff, but still holding lines I wouldn't have tried on my inbred 26er.
The other week I shortened it up to the 1136mm setting, & was suprisingly put out by the change. The single ride it lasted was bizarre & not a happy experience tbh.. It was on a horribly fast XC run, with roadie friend (?) & probably not the best of tests. So I bulked, pushed it back, but only to the 1141mm setting (going by the whyte spec's & the 5 bolt hole options, I haven't had the measuring tape out). It's surprised me how obvious even these small length changes have made themselves. Now it's definitely not as XC long feeling, & the backend is up to some interestly zippy (sorry) stuff.. I am still toying with extending it again, as it felt more of a mile muncher. i'm holding out for now, as I know I will have to try the short setting again. Front end wise I'm happy with the geo, I like a more a relaxed front tbh, but am no gnarr DH god. The guys I ride with say I'm as fast downhill, as my FSer, but it still early days, & TBH I want to get my FS bike back out (that's got a wobbly rear wheel I just found) but am really happy playing with the 929. If anything it's my lack of experience with long term HT use of any type holding me back, as I love my full sussers.
I'll not go on about it, but I don't like 1x10 it sucks.
Need a new job & some proper gears.
I've not tried anything to compare it with 29er wise (yelli,bigwig,hi-lat), but I'm very happy with it, oh nothing fallen off or broken, though it seems the seat post keeps slipping down annoyingly
