Default Re: 3 Piece Wide Crank??

The offset cranks I got from Spooky Tooth were the same length as the original Schwinn crank arms (6" +). They fit the spindle just fine.

The problem with the one piece and a 1 1/2" bottom bracket looks to be the elbow won't fit through the small space?

With the short crank, the arms do not reach the engine and are below it. The arms clear the rear bolts on the Grubee mounting plate by 1/4" on each side even using a standard bolt (though 7mm, not the stock 6mm), a washer and an 18 ga metal plate to pretty up the plate.
Easy does it, but do it!
