Here's yer 650 single speed

Just how I like it.......med. size 2.35 tires and fully rigid setup. Its not mine but I have had thoughts of building something like this for myself. I do have around 35 bikes so maybe I'm not really in need and I do have a perfectly good 26" wheel single speed-as a matter of fact it was a cover bike on Mountain Bike action about 25 years ago . Still, I would probably be a little happier with bigger wheels. 

Anyway, this one is going to a bay area customer who wanted a good basic XT build - no carbon, no frilly fancy stuff....just the stuff that performs and keeps performing, The only boutique part is the Boone Technologies rear single speed micro-drive cog and the King headset. This bike is silent.
