Oh yeah, there's lots of room between the ring and the stay But even if there was such a thing as a shorter octalink bb spindle, I could only move the crank about 3mm closer before it hit the cup.

I'm going to find a double crankset, install it and see how it works out with an adjustable cub bb. I should be able to make it work...it has to be better than what's on there now.

shrimpx - what length spindle did you use?
