I know nothing about threadless headsets. What's a decent brand to get. Obviously Chris King will be mentioned, but this is a modest build-up with 9 speed 105 components. I only paid $100 for the NOS frame and fork.

What type of labor charge is reasonable to cut the steerer tube and install the headset?

Can I do this myself or this something I should leave to the shop? If it is not difficult what tools do I need?

Hi,

You can buy a 1" FSA Orbit X threadless headset from chucksbikes.com for $20. That's a good deal for a decent headset :) .

Cheers,

Thanks. That looks like a great deal. Now How do I figure out what the races are? (I see they have 27.0 and 26.4).

Where is this measured? On the fork or the frame?

Fork crown race seat.

Are we talking about that raised lip just above the unicrown on the steerer itself?

I did some searching and it looks like two different types: ISO (27.0) and JSO (26.4)

It's a kinesis carbon 3 fork if that helps.

Ever heard of a caliper? And your research sux...27.0 is JIS and 26.4 is ISO. The smart money would be on 26.4,but sydney likes calipers.

I would say that was unnecessary, but look who I'm talking too :rolleyes:
