Brand new Origin8 boost rear hub. 6 bolt disc, black, HG11 freehub body, 32 holes. I bought this on accident. Classic design; 3 pawl, 4 sealed cartridge bearing, hard anodized axle and hardware. It's a good hub albeit a bit on the heavy side, which I would guess translates to durability. HG11 freehub body; 36.58mm which can fit a mountain or road 11 speed cassette (as well as 10 and below with appropriate spacing). Not "HG11-MTB" (which isn't a thing; HG11 = 36.58mm. "HG11 MTB" is the same as HG10 and thus the moniker does little more than confuse ppl). Get a good deal on a good, new hub! Holler if you have questions (probably about HG11 cuz I probably just made it more confusing lol)
