Headset reducer cups 11/4” to 11/8”

[Dface]

I’ve got a pair of reducers that you put in a 1 ¼ headtube (37mm) which take it down to a 1 ⅛ (34mm). If that’s that you’re after.

They came out of a 90’s Cannondale.

Cannondale did their own 1&1/2" headset originally to fit the suspension in the steerer, aka headshok.
It's slightly different to the later 1.5" headset - stack height, insertion and bearings.
Additionally, I think the cannondale is actually 1.56, but believe it's adaptable if you're careful.
Fork length might be a challenge.

A True Dalester should pop up and clarify if we are lucky

Dan28, The confusion is "Cannondale" .. Not really
Yetichaser mentioned 1.5, which is a headshock standard at some point.

Cannondale also used 1", 1 1/8" and 1 1/4" headsets through the years.

As long as the reducer has a 37.0mm OD, and 34.0mm ID, it's what is need.
That's a 1 1/4" to 1 1/8" one. (or Evolution to OverSize)

Does anyone have or know where I can get headset reducer cups to take a 11/4” headtube down to 11/8” in order to use a 11/8” headset and forks

Thanks

PM me
I might have something
Bought a few bikes over the years that reduced 1 1/4 Yeti/Mountain Cycle/Manitou steeresbdown to 1 1/8
I’m sure I’ve got a bag of them somewhere
