I usually try to put profile cranks on my fixed-gear builds. I only with their limited editions and raw finish cranks come in 165mm. Just make sure you use the right spacer depending on your bb width. Chainline usually isn't an issure with bmx type bbs that have spined spindles. I'm considering respacing some 110 mm profile rear hubs for SS use. I'm pretty sure the OLD is the same for front hubs, I've seen 100mm listed for many bmx hubs. I've had a craving for brown anodized parts since I've been ordering parts from dans comp.

The nice part about the compact drive movement in bmx is that the older parts are getting cheaper. I was able to snag a Shadow Crogora 44t chainwheel for about 20 bucks with 110mm chainguard.

Profile offers spiders for their cranks that have 110mm bcd, 104/94bcd, and 4 bolt patterns. I prefer using bmx parts because you can get them at a decent cost, they have better color selection, and they don't look the same parts everyone else is using. I like my parts burly, and don't mind the added weight. Profile's coming out with a fixed gear hubset, but I think I'd rather get Phil's for that money.
