If I was not happy with these choices, I could add a link to the chain and switch to a 45/17 --5.45 (71.5" / 5.72 m) If I added two links to the chain, I could get the same axle position with a 48/18 --5.49 (72.0" / 5.76 m) | If I was not happy with these choices, I could add a link to the chain and switch to a 45/17 --5.45 (71.5" / 5.72 m) If I added two links to the chain, I could get the same axle position with a 48/18 --5.49 (72.0" / 5.76 m) | ||
Half | [[Datei:Half-link.jpg|right|Halflink einer Kette]] It is also possible to use a special "half link" or "offset link" to lengthen or shorten your chain by only 1/2", and adjust the sprocket-to chainwheel distance by 1/4". Half links are available for both 1/8" and 3/32" chain. Not all chains have the same diameter rivet pins: use a half-link of the same brand as the chain, or at least check. | ||
Another possibility would be to do a little bit of filing at the back of the dropout to let the axle move back just a bit. | Another possibility would be to do a little bit of filing at the back of the dropout to let the axle move back just a bit. | ||
It is also possible to grind or file a flat on each end of the axle to allow a bit more adjustment, like this: | It is also possible to grind or file a flat on each end of the axle to allow a bit more adjustment, like this: | ||

I used a more drastic solution on my Bianchi Osprey. I cut the rear axle short so that it didn't protrude past the surfaces of the locknuts. Thus, only the quick-release skewer went through the dropouts. Since the skewer is quite a bit thinner than the actual axle, this gives me considerably more adjustment room. | I used a more drastic solution on my Bianchi Osprey.

Eric House has prepared a whole web site devoted to the problem of finding sprocket combinations that will work with vertical dropouts. He has developed charts and Java applets that show the options available for particular chainstay lengths. | Eric House has prepared a whole web site devoted to the problem of finding sprocket combinations that will work with vertical dropouts.

If you're converting a '90s mountain bike to singlespeed or an internal-gear hub, chances are that it has vertical dropouts, and you'll most likely need a chain tensioner of some sort. There are two different sorts of chain tensioners that you can use. | If you're converting a '90s mountain bike to singlespeed or an internal-gear hub, chances are that it has vertical dropouts, and you'll most likely need a chain tensioner of some sort.
