Z-Rims 'age'

Looking at the z-rims on my vintage redline. The dates both end in 'C'. ( 4-11-c and 4-12-c). Anyone know what the year would be? They are black and stamped z-rims.
Thanks.

Wow, hadn't thought about Z Rims in a long long time. Those are the ones with the circular hole between spoke nipples that showed the metallic rim tape, yeah?

If the wheels I am thinking of I recall them being around in the early to mid 80's. Typically hard anno black with either silver or gold tape showing through. I had issues with them personally in that they simply weren't as strong as the comparable Araya and bent/warped a set or two.

Juan,
The set of Z-rims here are the plastic ones that laced into a wheel and would deform on landings and then spring back into roundness and true. I'll try to post a picture later. Smiles, MH

These were aluminum rims created by Mongoose that used a special Mylar strip to keep the tube in. Really designed to race.

Think they would both be late 1984 rims.

Mongoose Pro Class rims are what you are describing it sounds like


Z rims are the original plastic rim which was put out by ACS, maker of the Tuff wheels

Yup, Pro Class. They were astoundingly easy to warp, but light for their time.

I can recall a type of mag (not rim) that were designed to be put into a freezer to bring them back into true but can't recall if it was the same group.

Yeah, Missed that first part of the post. I had Z rims, by ACS. Didn't like them to much after I built a set with some 105 guage spokes and shrunk the rim where the tire would not stay on. Settled on the Araya Aero bmx rims instead. Those made sweet wheels.
