|Getting road cranks (double) to work on track bike||Sprint-Nick|

|Anyone have any ideas how I can get road cranks to work on a track bike with the chainline? I'll leave the chainrings (or a chainring) on since track chainrings won't work on it. I want to use my old frame (yes the damaged one) for road riding and put a brake on it.
Thanks in advance.

|I use the inside mount for the ring and get some track/bmx chainring bolts. Mount the chainring as if it had the outer ring on (i.e., the inside of the crank.) I have 2 fixies set up like this and I've had no problems.|

|I'm using a vintage Dura-Ace road crank on my track bike. I'm using a rather small Dura-Ace BB (103mm, I think). The chainline is fine when using the "outer" chainring but I did have to use my trusty Dremel tool to cut off the lip that helps hold the inner chainring in place (FYI it was rubbing against the chain stay). As for the chainring bolts . . . I used my trusty Dremel tool there also.
The most important thing to remember is making sure you are using the right chain/sprocket combination. If you use a 1/8" sprocket with a 1/8" chain on a road chainring you'll get a lot of noise. A 1/8" chain will work on a 3/32" chainring. I'm sure this combination will wear out your chain and chainring prematurely though. Just make sure you get a 3/32" sproket.

|The most the chain line could be off is half the distance between the chain rings. I doubt this will be an issue. Are you using 1/8" or 3/32" track chain? I would think the bigger worry would be the narrow rings and the wide chain. What you most likely need is just some track chainring bolts (shorter than road) and then you can drop the inner ring. You can't drop the inner ring while using the existing bolts unless you can find some washers to take up the XS length.|| |
