I'm having trouble getting this to post. Let's see if this works:

I have an OMAS headset on my Colnago Super, and I know I wasn't supposed to do this, but my friend and I covered it in a rag and used an adjustable pliers on the headset... Now it's marked up pretty bad, and I'm wondering what exactly an OMAS headset is that I wrecked. Asf ar as I can tell, it's imitation Campy. Is there any way I can get a replacement top thing? The other parts of the headset are immaculate, and so was the top until we screwed that up. =/ Just curious how much damage we did. Man I feel bad about marring up such a nice looking headset. Seems it's rare, too, cause I can't find much info on it.

You will have a hard time getting another. People here have said OMAs was an upgrade at the time to Campy. I just got a bike recently with the OMAS headset. since there isn't any text on the flat sides, can you polish it back into looking good?



PS, get some proper tools.

I don't think polishing will fix it. Take a look for yourself: https://kyledr.mine.nu/colnago/headset/

Damn that is jacked up.

At that price and other OMAS parts, I should part my bike out. OMAS cranks, Galli parts, geez

OMAS specialized in lightweight parts, alloy, titanium, coloured anodizing and such. They were considered an upgrade, but if you actually had and used OMAS parts back in the day, you usually found out that they were pretty delicate. This goes particularly for the headset. The hubs are pretty good though.

And, yes, get some good tools. Although, even with the proper headset tools, and the use of a rag in between, I managed to gouge alloy lockrings. Not as bad as this though! The alloy is just very soft, and many people used a steel lockring instead.
