looking for info on offset ground cranks I've spent about an hour searching and cant find jack squat. I know years back they were talked about quite a bit, but I can find no information.
does anyone know how much it costs, how much it increases stroke and how much it weakens the crank?
this would be for a strickly NA application.
TIA

I know TSP used to have a offset ground crank option. I believe they gained about .100" stroke on a stock crank. When taking a 2.100" journal down to a 2", I don't think your really "weakning" the crank to much. Alot of high perfromance cranks run 2" journals. I do believe they need to be re-heat treated after cutting though. Not sure on the cost, but there are some nice rods out there for a 2" Journal.

cool, thanks. I'll give TSP a call.
if your going from 2.1 to a 2" journal that is only a .05 gain in radius, so I beleive that is only a .05 gain in stroke.

The reason they don't do it much anymore is because the cost of stoker cranks has went way down when eagle started selling cranks. For the same cost you can have a 4in stroke. I was looking into it as well.
