It's super exciting to see Niner getting close on their 6.5" travel freeride 29er! While I don't see picking one of these up myself very soon, I could in fact see ditching my DH bike, and using this instead. MOre versatile, pedalable, etc. I could use this at placed like Black Rock, Tahoe/Northstar, Whistler, etc. And, for what I'm after these days, it'd be sweet. I'm not as into doing the big drops (well, what were big for me, at the over 6 foot range, but below 10').
This bike has some really well thought out bits: dishless rear wheel, use of Maxle oversize axle and QR in on rear wheel, very short chainstays, etc. Go check it out, this is going to be a superb ride.
