Now, I admit I'm just eye-balling this but I would guess there's at least 3/4" of an inch of full thickness aluminum from the inner most portion of the existing threaded hole to the scallop. Could be more. Either way, I'll probably take some measurements after work this week.
Kind of surprised regarding the Shimano recall. I guess they don't figure it's likely to be a life-and-death kind of failure.
The current ones for sale no longer have the issue. They don’t catastrophically fail unless maybe you’re a 2200W Olympic sprinter, you can see them starting to separate. It seems to be caused by galvanic corrosion between the steel axle and aluminium arm.
