I'm also looking into building a 27.5" SS hardtail or rigid MTB. Been rocking an early 00's Gary Fisher SS hardtail for about a year, that I picked up used super cheap just to see how I liked SS MTBing... and freaking love it. Don't even have a frame for the new rig yet, but just ordered this handlebar for it using a Christmas gift card I got:
