Please help!
I'm trying to convert an old bike to a fixie, but alas, it vas vertical dropouts.
I need an eccentric bb, but is there any eccentric bb that will fit on a frame that uses a 68x113, thank you so much if you can help me.

An alternative is a tension device. If you search single speed tensioner, several links show up.

Still, that would look a lot nicer than a chain tensioner tacked on. That always ruins the "clean" look of a fixie, and makes me roll my eyes and think "Ya just couldn't find a frame with horizontal dropouts, huh?"

Oh, that's right. Even the unsprung ones can't handle the back pedaling force. Guess the ones I've seen pics of were single speed freewheel bikes. Still looks goofy.

There is the Philcentric bottom bracket and you may still have to use a half-link. The added kicker is it is for outboard bearings only so you are limited to the crank you use but it will work.

Thank you all for your replies! Also Timmyt, I think I'm almost there it's either 16x43 or 16x44. No w need different advice, do I NEED perfect tension? One ratio is super tight, no slack, and the chain makes noises, the other is really slack, but the chain stays on decently. If I had to pick, what should I go with? Too tight or too loose? Can this hurt my bike? (Also I can't use a tensioner because it's a fixie)

Folks are helpful here, but you might want to try the Singlespeed and Fixie forum instead of C&V next time.

I think the chain should be loose enough to move a half inch or so up and down. Having it too tight is inefficient and feels pretty terrible. Having it too lose, it can come off. If you go this route, keep it well lubricated, because it won't take much wear to mess up the perfect chain tension.

I am actually using a half link chain 
I think I'm gonna go with the looser of the options, but I ordered a 44t chainring, if it's loose at 43t do you thing it might end up just right at 44?

Of course that's what the bike looks like.
The chain is far too loose.
