Well hullo everybody! My name is Caleb Lambert. I'm in Nelson BC, some hours north of Spokane WA.
I am a novice working on frame #3.
I've lurked and lurked, but today I'll ask my very own question(s).
uh, I had the Idea of building a bike with an 1 1/8" integrated Campy headset.
A little unwisely I bought the Campy headset, the park tool cutters for it, and the non-tapered 1 1/8" Columbus three piece integrated headtube from Nova all at once.
I didn't notice the difference between the Campy and the Columbus headsets. And I didn't notice that the Columbus headtube seems to be designed to take the Columbus/Cane Creek IS41 A-head set, not the Campy one.
the OD on the Campy cups is just under 42mm, the Columbus under 41mm.
they both feature the 45deg bearing seat.
So I've got the cutters for the Campy standard and could open the headtube rings with the 42mm cutters.
that wouldn't leave a lot left of the outside wall of the HT ring (but maybe the outside wall is just acting as a dust cover?)
And anyway, the OD on the headtube rings is 44.5mm and the OD of the topcap for the campy headset is 46mm.
the 1.5mm difference wouldn't look right.
Why on earth does the OD of the Columbus headset also come to 46mm if it is presumably the headset that the headtube was designed for?
The Columbus TAPERED headtube has a 46mm OD on the top half, but not the straight 1 1/8" HT that I have.
Whaaaaa?
I'm wondering what are my options, short of making my own parts on a lathe.
Does anyone sell an integrated HT for IS42 with a 46mm OD?
Is the lesson here "if you want to use an integrated Campy headset you'd better have a way to turn your own headtubes."?
Henessey, can I jump on your lathe?
Thanks in advance...
Caleb
