need assistance inferring my grinder's fork/steerer spec

[wallymann]

looking to upgrade to a TA fork...here's the OEM tech drawring of the HT...wondering if anyone can help interpret/validate what i should be buying.

upper bearing spec is 42mm OD, which equates to 1.65"
lower bearing spec is 52mm OD, which equates to 2.04"


i *think* the OEM fork is a tapered 1-1/8" to 1-1/2" spec...yes?

You are correct, sir. Last headset I bought was exactly that size. The fork was tapered 1.125 x 1.5
