Billet crank arms for cotter key cranks

Might be an interesting update for an old european bike:

The only problem is how do you attach your sprocket to it? Not to mention it's kind of fugly. Too bad they couldn't just leave them bare aluminum and make them kind of resemble cottered cranks instead of being so beefy looking. They also have cheap drum hubs also as I found that place before on one of my motorcycle forums I post on.

I think I would switch to a modern shaft instead.
