Hi all,

I recently rediscovered an old Austro-Daimler AD Inter-10 in my garage and have been thinking of resurrecting it as a fixed-gear commuter/urban bicycle. Thankfully, the original paint and chrome is still in great condition, along with the seat and stem and headset.

Since it's a nice frame and I have some time coming up where I'll be able to work on it, I wanted to spend some time giving it a little TLC and fitting some quality components to it. What's irking me now is trying to figure out the correct bottom bracket/chainring/crankset thing...and dealing with the issue of proper chainline.

I'm interested in a Sugino 75 crankset and I've been watching Ebay trying to pick one up on the cheap(er), but am wondering if one has to use the expensive 75 BB or can get away with something else, something cheaper? Something sealed?

I see the 75 has a 109mm spindle for a proper 42mm chainline; would it be possible to use something like a Shimano UN-54 with this crank? I figure for that one extra mm I could shift the hub slightly and re-dish the wheel, since I'll need to do that anyway after I lose the cassette hub that's currently on there... Is there any reason why this wouldn't work? Has anyone done this?

One: The Shimano BB is a lot cheaper
Two: It's sealed (rain, snow, dirt, salt, egh...)
Three: I already have the tools to work with the Shimano style BB, but not those for the 75

Thoughts? Suggestions? I've seen some things about a Sugino "MS-68" BB, but haven't been able to find them for sale anywhere, nor any info about them on the Sugino site.
