Title: Z-Rim dates?
Post by: Mikku on April 14, 2014, 01:21 PM

Hi guys! Can anyone help me to decipher the date codes (assuming these are the date codes) on these Zs?

Front rim

Rear rim

Both together

Thanks in advance!  :daumenhoch:

I have 2 sets of early z-rims, and neither look like that, one is printed neatly and the other in white marker but is clear to read.
I see what you mean, not easy to tell the year with what you got.

Yeah, it's a tough one alright! Assuming it's a 3-part date code, it looks like a 2, possibly followed by a 1 (on a slant!) but I've no idea on the last one (year)!!

last one's strange ...... its deffo a letter, as iv'e seen a set with "8-18-B" (http://bmxmuseum.com/forums/viewtopic.php?id=134495), and another with one wheel "7-30-A" the other wwheel "7-30-B" :crazy2: (http://www.vintagebmx.com/community/index.php?&showtopic=27064717). Also seen a set with "7-31-85" (

/>
....judging from this, the first should be MONTH, the second should be DAY, but stumped on the letter, because of that set with A and B :(

I was looking at one of my 80 z rims  this morning and your date could be .

A =  January
1 = 1st
2 = 82

as they tended to work backwards with the dates. :daumenhoch:

That sounds promising!  :daumenhoch: So did yours have the same type of stamping as mine?

Here are the replies I got on the Museum:-

Don't know really but if they have no z-rim transfers on the brake pad areas they are before 84 anyway
