Ultimate rear hub for touring.
I was given an old bike and discovered it had a very unique hub. It's made of 4130 steel and has keyholes for spokes and allows you to replace spokes without removing the freewheel! I'm stoked over this thing! No more hauling around a chain whip, lock ring tool, and wrench! It does weight more than my current aluminum hub and cassette but when you add the required tools to remove the cassette the weight will be reduced. Here is a drawing of what each keyhole looks like and a photo of the hub (before I remove the old rim and rusty spokes).
I'll be getting new a 7-speed freewheel, spokes, rim, and QR axel for this hub.
