Eddy Merckx Frame Identification

[Stj]

Thank you for sending that. That looks like 70 degrees roughly which to me seems pretty radical but he was a tall dude.

Hello Cycling Friends.

I recently accidentally purchased a 7-11 EM frame, and I'm working to restore it. The BB code is L-7X--B-3375. My research is that is is a 1989 7-11 team frame (correct me if I'm wrong).

Anyway, to where I need help. A friend of mine gave me a 1" threaded headset. The threads of the headset-bearing-cup fits the threads of the fork. However, I can't get the upper and lower -bearing-cups to fit into the frame. It is like they are 1/16" too big. Also, I can't get the fork-crown-race to sit at the bottom of the steerer tube. Again, it is like the flange on the bottom of the steerer tube is slightly too big for the fork-crown-race. The headset is branded as "OFMEGA", which I have never heard of.

Any advice?

NCSU... all the EM frames I know use ISO specification... you have something else in there.

Ofmega is an italian manufacturer, think they went out of business long time ago. Their headsets should be ISO but who knows at this point.

GEt a good caliper and measure that really well, btw... a caliper in metric. One in inches will make eveything way too complicated.

B3375 L7X - Corsa Extra SLX/SPX 1989, full "technical" designation does not indicate that it is "team bike"

Ultraman6970,

No, apparently I've never installed a headset before. All I needed was a bearing pusher to seat the headtube cups. I have installed the headset. Just took a little mechanical advantage and grease.

However.....
.... my steerer tube is too short. I'm assuming the headset I'm using is too tall. Does anyone have a suggestion on a low-profile threaded headset?

Thanks Emerxil.

I'm assuming it is a team edition as it is painted such, and appears to be original paint.

Shimano 600, Dura Ace, Chris King two nut. All low stack.

Two low stack headsets I use are the Tange Passage and Tange Levin. The Passage is the lowest I've found.

Take the headset off that you have on there, including the cups.

Put the fork all the way into the headtube. Measure the part that sticks out at the top. That measurement is the amount of stack you have available, and it will tell you what the maximum stack on your headset should be.

Alternatively, if you don't want to take off the headset cups, measure the steerer tube from the crown (bottom of crown race) to the top of the steerer tube threads. Then, measure the head tube from end to end. Subtracting the numbers gives you the stack height.

The first method eliminates parallax or other errors, so is better. The second method will get the job done, too.

Once you have the measurement, you can get the headset you need. I have a very low stack black Shimano 105 headset here if that interests you.

Looking for some info on my Merckx Corsa Extra SLX. Obtained in the mid 90's.

"?" & "OX" on left side of BB (when looking at it), "B" over "3419" on the other side.

Thank you!

I'm very appreciative of the information that's made available in this thread. I have been an Eddie Merckx fan for many, many years. I enjoy seeing the variety and details of the bikes and frames here. This is a respectful request that people posting here include a picture of the frame or bike in question, regardless of condition, to allow others to see the features of the frames offered through the years.
