Ok, so I'm a dork. I got the weight of a XT hub, cassette, and Der. Total: 960g. The XT hub itself is 435 (for single speed comparison).

Ok, so not sure if I'd spring for that, but it'd be fun. I took a look at my Kona's stock wheels. They're soon to be replaced. The disc mount got me thinking. I'm going to use V-brakes, with a karate monkey or something. Then I'll do SS cassette cog. Then how about bolting on a disc cog and running it as fixed/free??? I could space the BB and cassette cog so that they're in-line with the disc cog:) It'd be fun. Disc fixed, 2.55 WTB Weirwolfs, and snow?!
