Is my fork 1" or 1 1/8th"?

I'm looking for a new headset but am confused as to which size my fork is.

It's the threadless fork off the Condor Potenza 2009 frameset. The headtube of the frame measures 1 1/4th" while the fork steerer tube measures 1", such that for ahead stems like the Deda Logo I require a shim.

Am I looking for 1" or 1 1/8th"?

Thanks

Cue someone posting a pic of a ruler, typing UTFS or just being generally ill tempered and winding themselves up for no good reason. Yawn.

I've measured it, so pic of ruler won't do much.
I've UTFS, Googled, etc. and come to the conclusion that 1" is the less common size on more recent frames.
I would hope mine is the more compatible 1 1/8th size but my measuring tells me otherwise.

1"

i think there is a good reason, considering he has measured it and discovered it to be 1"

What are you on about? I was referring to the typical response to this kind of entirely reasonable post.

In that case, I'm greatly limited in my choice of headsets...

I should be measuring outside diameter right?

Sorry guys, silly thread.
It's probably a 1", but I'll double check with Condor tomorrow.

The fact that 1 1/8th is the more common size for forks today is what threw me to start with, especially with there being so many more 1 1/8th headsets on the market.

UTFS

Fuck wits.

yes, there would be good reason for someone to give a sarcastic response.

Many of you might know that I'm at least a passable mechanic.

You might be surprised to have discovered me at home a few evenings ago looking at a fork that has come into my possesion and not being able to acertain whether it's a 1" or an 1 1/8" as I seem to have no tape measures in the house.

However, if I did have a tape measure, I wouldn't let my wishful thinking allow me to measure it at 1" and post up something about it possibly being an 1 1/8"

sorry if i missed something....

Surely the question was "Is the 'size' of a fork just the diameter of the steerer, or something more complicated", which is a perfectly reasonable question, given a 700c wheel is rarely 700mm in diameter, and seat post lengths can be c-c or c-t, and a 25.4mm handlebar normally takes a 22.2mm brake clamp.

Tsk.

I contacted Condor about it yesterday. The man on the other end gave me a quick respsonse of 1 1/8th", which, I guess, is the standard nowadays? To that I mentioned I had measured the steerer tube diameter to be closer to 1" than 1 1/8th" and he asked me what frame it was and what year it was produced. He put me on hold to ask a colleague, who confirmed it was actually 1".

I was using that crappy IKEA paper tape measure, which made it difficult to measure the diameter because it's hard to judge where the exact centre of the tube is.

A cheap plastic vernier caliper is a godsend in cases like these. Just sayin..

the main give away was the fact you need to use a shim
