Hey, I'm hoping someone can give me insight into whether a Merckx on eBay is legit. I've been googling a little and have no reason to question its authenticity, but I don't know much/anything at all! There's no photo of the bb shell so I can't compare it against the tables I've found online. I've messaged the seller and am waiting to hear back if they can send me a photo.

I can't post a link yet, but it's ebay dot com /itm/Eddy-Merckx-Corsa-Extra-SLX-Campagnolo-Chorus-Triple/284144951763

And yes, I know the price is high for what it is, but it's for charity, which seems like a win/win: get cute bike, support kids. Thanks in advance!

Many thanks. Hope that happy evening the day before didn't affect the quality of his work :-)

Two Decals, Interpretation

Hello- there is a decal/transfer/sticker on the seat tube of my EM Corsa Extra that reads "fietsen erleyses terafene." I ran it through a translator, but that wasn't a ton of help- "cycling erleyses terafene." Can you please tell me its significance? Could it be a local bike shop?

The second one says "Original Painting, Eddy Merck, Zinc Phosphate, Anti Corrosion Treatment." Would this have been an extra cost / an extra option, or was this decal applied to all EM's made around 1998? I've not seen either decal before this frame. Side note, I bought the frame from a seller in Italy. Thank you.

If you change "terafene" to "teralfene" you give me some chance - it's a town close to the Brussels - Ghent route.
The sticker "Original Painting..." was introduced in 1996 and used until the end of steel frame production (sometimes a shortened version was used when repainting the frames).

Another one..."A" (only) stamped on the drive side, Campagnolo dropouts, repaint. Based on my education from this site, somewhat early in the Z production group, so 1985? Thank you!

A Z1154 End of 1984
Warning! not sure what it is: late Professional or Pro (753 or SLX) !
Precise research advisable...
...i.e. examination of the inside of the tubes visible through the BB cover and steering tube
...and more photos in general

Hello- No internal ribs, and 2 more photo's. And another question. Would a 753 Pro be more valuable or sought after than a SLX "Professional?" This is a repainted frame BTW.

Pro 753 is rare, lightweight and unique
Be sure to check out the markings on the steering tube....

Z 1701 info

Hello. I recently acquired Z 1701 from the original owner. He raced it 9/84 at a sanctioned race here in CT. He knows he bought it before that race, he believes it was the spring of 1984.
The bike was purchased at Buzz Cycles in old Geenwich, CT.
Left side is 5 P, right side Z 1701.
I know the dates the original owner mentioned dont line up with other Z run dates mentioned here. I wonder if purchase dates on some Z frames are a good bit later than build dates.
My seller was the original owner and is pretty certain he bought it in the spring of 1984 because he has the flyer from that race and he was in that race with his Merckx only one year.
It has under bb cables, sloping crown and 84 stamped cranks and rd.
He and his brother both bought Merckxs and groupsets at the same time from Buzzs.
The bike sat for the last 35+ years, I restored it.

This is a sensational surprise to me, but... a few small details need to be clarified.
If the Z1701 was bought in the US Spring 1984 then it must have been built at least 2 months earlier - this means a production date of March 1984 at best.
The frames built for Team Panasonic for the 1986 season are known to be Z45xx - they could have been built as early as September 1985.
This means that in a period of 1,5 years about 2800 frames were built, so the average capacity in this period is less than 1900 frames per year.
In his statements in 1989 Merckx emphasized that from 1982 onwards the number of frames built increased steadily (year on year).
By the time the Z1710 was built, about 13500 frames had left the EMC factory - if it had been built in spring 1984, the average throughput over the 4 years of production (from spring 1980 to spring 1984) would have been about 3400 units per year.
A drop from 3400 to 1900 would have been an easily seen disaster.
If the Z1701 had been built in the spring, the pro teams would have used the Pro SLX or Pro 753 (and they were already in production, their designations are often earlier than the Z1701) as early as the 1984 season - yet they were not used until the middle of the 1985 season (a year later)
The only thing that would help is a proof of purchase with date and serial number.
Starting in September 1984 on this bike (if it was bought "the day before" it would have been built in July 1984 at the latest anyway) changes our numbers to 3000 and 2400 - still doesn't look good and doesn't solve the Team Pro SLX/753 problem.
My dating (would be December 1984) gives numbers 2800 and 3600 and fits the Pro SLX/753 problem - but is not supported by any document....
Dating 1980-1984 is a nightmare

Z566 (see pic below) has been determined to be Pro SLX. Originally thought to have been born in Q3 1984, it will be interesting to see if that date gets pushed back somewhat...

Cyclesmakaron aka Jacek - I am so appreciative of the work you have done. I reached out again the the recent seller of Z 1701 for more definitive information.
He is in the process of scanning boxes of photos and hopes one will be in there of the bike with a date on it.
He was once again (third time on this now) quite certain he rode the bike in the scanned photo of that race in 9/84. He kept the flyer all these years and while we all know memories can fade, it is clearly his strong belief he rode the Merckx at that race.
He also told me he was going to call his brother this weekend who bought a matching Merckx from the same shop. They ordered the frames and group sets together from Buzzs. It has been some time since they spoke. He hopes his brother can provide more information.
Im hoping his brother might sell me that bike too.
I know your research has been very exacting. I only offer what I know and hope to provide more.

I'm very interested in more information and don't mind a little revolution in EMC dating
Assuming that Z1701 was built in March 1984 the construction of Z566 would have to be postponed to the end of 1983... that is before SLX went into production.
In this situation introduction of SLX to team frames only in mid 1985 would be completely incomprehensible...

The original owner of Z 1701 sent me a photo he has kept of himself on the bike at the 9/84 race. The kicker is, its not dated. He says it is that race and he only rode that race once.
he is checking with his brother for more supporting info this weekend.
Just remember, I have no opinion on this. If its and 84 or 85 its a cool bike.
Im passing along what I learn.
He even remembers the announcer of the race that day. The gent was well know but that seems to me to be a lot of recall.
