Just one day after SingleSpeed nationals and the gears have gone back on my hardtail already as really; I am a bit soft. But there is something to be said for the simplification that less gears brings. So while the buzz over XX1 groupsets continues, I started to search for a more affordable option and here it is. Chainring from wolftooth components married to an XTR clutch derailleur. Solid, quiet, simple. Highly reccomended.
