So I jumped in and purchase the Sight C2 29.... could not be happier.
After 3 weeks of riding pretty regularly I can confirm it is as they say in the video above... it does everything well.
Main thing that I am enjoying is how easy the bike is to get off the ground, wheelie and manual etc. Something that I struggled with on the Fuel. IMO there is a lot more going on with how easy a bike is to manual than the chainstay lengths. Considering the Fuel = 432mm and the Sight = 435mm, I would say the sight is twice as easy to get the front up and therefore very playful, on par or maybe even better than my last bike (remedy 27.5). More to do with overall rear suspension kinematics than chainstay length alone.
It is not as plush as the Fuel EX over small chattery stuff when sitting and pedalling but is hands down a better descender, handles the steeps with so much ease and stability.
Spec is awesome, the usual suspects will be promptly changed out, grips, saddle, maybe bars.
Got the bike for $5700.... could not see even close to that value in the competitors offerings, and besides the value this frame just rips.
