I remember BITD that people used to say if you bent Z-Rims, all you had to do was stick them in the freezer and they'd pop right back to true. Can anyone verify the the validity of this rumor, or is it a BMX myth? Personally, I never knew of anyone who actually tried it. But it seemed to be known far and wide that Z-Rims would magically true in the freezer.

Never had Z-Rims, not looking to ride any Z-Rims, just wanted to start a new topic. (Hope it hasn't been discussed too much before!) So what is it -- myth or reality?

That's a much discussed myth/urban legend. Other people heard the same about tuff wheels. If that was the case then people in the northern states would have true wheels every Spring... lol.

MYTH BUSTED!!!

Are you kidding?? You can't tell me that you or some-one you know didn't try it. I got in a little trouble for trying it. The only way it would fit was if I left the ice cream out.

All you get from putting a bent Z-rim in the freezer is a cold bent rim.

I only had one friend who owned Z-Rims, and he thought they were such piles of crap that he got rid of them in a matter of days. (Or maybe it was a couple weeks -- or maybe they were on his bike that got stolen in a matter of weeks. Seriously he had a white 87 GT Performer with what was the new "S" frame that was stolen only weeks after he got it). Anyway, no one I know ever tried it because no one rode Z rims for any length of time. That photo in the link you gave me pretty much says it all with those things from what I remember -- flex city.

Come to think of it, I wasn't a fan of too many ACS products, the RL Edge wheels and tires being the exception. I never had many problems with the freecoaster (more problems with the coaster brake mechanism in the hubs themselves breaking from the abuse of flatland riding), and I used the pro rotor and 55 stem just because it was stock on the Itson Stroke Zone, but I liked the gyro better. It just seemed ACS made a lot of products that were prone to breaking BITD.

Anyone have any idea where the freezer myth came from?

First off, I'm not sure where the freezer thing came myself although I used to hear that alot and also "if you hung your bike upside down by the z rims(for winter or storage) they would be out of true" as to this ...... Anyway, no one I know ever tried it because no one rode Z rims for any length of time. That photo in the link you gave me pretty much says it all with those things from what I remember -- flex city. ............I raced my z rims bitd for almost 3 years and the whole reason I loved them was to do just like that picture!!! Everyone always wanted you to do a kickout hard enough to bend your wheels. Yeah they never stayed that true and I went threw a lot spokes and innertubes but hey that was the point of z rims anyway...try that trick with some aluminum rims or mags. Oh I also just finished off some icecream so I may go try this theory out myself..lol

I remember reading this topic in BMX Plus BITD and I never owned any ZRims.
So I would point the finger in their direction of giving this rumor some legs.

That dude in the link doing a kickout was exactly what I remember they would do. I knew of people that cracked their Z rims from doing just that when it was cold outside.

-logically speaking it makes sense (at least in my head) that if you had a bent rim, the opposite should hold true-meaning use a little heat to soften the composite up than cooling them down to set. not saying sticking them in the oven is a good idea, but what I envision as making this work would be to flip the bike over on its bars/seat and spin the bent rim- apply some heat, hair dryer or similar and see if they straighten out..
One thing I cant figure out is how heat or cold would fix the broken/bent spoke ..lol

oh well, sounded good for a minute.

About that link- Its not exact because ACS was making z-rims long before '85.
I got a NOS red pair in my garage with a matching born on date of july 20 1980

So what year were the first Z-Wheels produced? I have a pair of White Mike Buff Z-Wheels that are stamped February 1984.

good question. I dont know man, but like I said, mine has a 1980 date stamped inside. Are NOS and certainly do not have any writing on the sides- also they have sunshine hubs. so I dont know what the timeline on ACS- can only attest that the article is not completely accurate.
