Has anyone cut them open or had the misfortune to see the cross section unintentionally?
I'm looking at dabbling with super short cranks and as I have SLX cranks already, they look ideal to drill and tap further down the arm. From rough measurements this would give about a 150mm length. I would consider getting steel inserts too as I've noticed some models of SLX have them.

Not so much but exactly the info I needed. Cheers.
Zee's aren't hollow if you're after something to modify.
Good call DD
Zee are also heavy, Deore is lighter and is not hollow.
Not sure there will be enough thickness left on a Deore to shorten to 150mm. Depends on the application I guess.

I've got some old XT like the ones in the link it they will do. Just have shimano written on them as they are of a specialized.

150mm cranks (5 bolt and probably road...)
