scrap steel is about 20c / kg
scrap allum is $2 / kg
(good prices, often it's half that or less).
Rims are around 400 grams
The hub shell is maybe another 100 grams. Those are allum. Spokes and the axle parts are steel.
So you cut all the spokes and pull the hub apart and you have about $1 of scrap metal.
The reason to do it is to acquire cups, cones, straight axles, and spacers to repair or modify other wheels. Having a lot of spacers from junked cassettes is also helpful for SS conversions.
Cutting the spokes etc makes storing the scrap neater.
And hopefully your metal recycler doesn't notice the steel eyelets on allum rims and say it makes all your allum dirty.
The easiest way to stack up scrap $$ with bicycles is shit (heavy) aluminium bsos but tearing them apart is not really worth it or satisfying because none of the parts are useful.
