Yowsa , thems some spendy TAG mags , the "sacrificial casting" method they claim to use to make each wheel is interesting to say the least....I wonder what steel alloy has a low enough melting point & the mechanical strength to keep it all together when 4 pounds of hot liquid "composite material" is injected into the mould & let set. Once the composite material has set , they then re heat up the entire wheel to get the now molten metal "mantle" to pour out of the "composite material" wheel..... Someone at TAG is both a metalurgical & polymer casting wizard.
Nothing like the way Tuffs are made , eh Ed ?
"Lost Core Molding" great marketing buzzword for what is essentially a 100 to 1000+ year old process called "sacrificial casting"
They remind me of my 20 inch 5 spoke THUG mags which are cast in 2 halves then joined together, you can clearly see the join on the THUG's but I could probably sand & polish the join out if properly motivated , a trip to their manufacturing plant would be very enlightening to anyone who has even a mild interest in casting "stuff"
I don't think I'll be buying a set of TAG mags to throw onto my 26inch GT cruiser at any price.
I did a scaled down experiment on my Totally Aerodynamic 20 inch bike by fitting aerodynamic mags to it.

A paradox & conflict of interests to say the least.
I'm pretty sure that the TAG wheels will work on my 1982 GT
