Help me understand what type of headset i have?
 

On my Felt, I have an FSA integrated headset with a non-tapered 1-1/8" steerer tube.
I'm trying to find its equivalent with other manufacturers, since FSA does not sell lower stack height dust cover.

The dust cover is 46mm in diameter.
The top bearing's external diameter is about 41mm
The internal bearing is marked:
TH INDUSTRIES1-1/8"
ACB 36 degrees x 45 degrees 873#

I believe this is the headset - the FSA Orbit IS Carbon: http://www.fullspeedahead.com/produc...rbit-IS-Carbon
I believe these are "Cane Creek Standard".

So,
How can i figure out which type will work from other manufacturers?
Since this headset is "Cane Creek Standard," does that mean that all Cane Creek headsets have those angle measurements?

Any integrated 1 1/8 headset with 36x45 will work with your bike.

Or in another words... any 1 1/8 cane creek spec will work. If somebody offers you a campagnolo one say no, the specs in the bearings are different.

Look always 3 things...

Integrated headset...

1 1/8

36x45 bearings.. those 3 things will give you a matching headset for your bike.

the cane creek and Chris king sites talk about internal bore. does that change things?

Have you tried this? http://www.canecreek.com/headset-fit-finder

Integrated headsets have two standars... campagnolo and cane creek... your bike is cane creek spec... dont get complicated man, we can be talking headsets the whole week. The bore ID of the front tube are standardized is not something the manufacturer came out of the blue.

Yours is cane creek.. done with the subject.

tl;dr

use a bluetooth/thread
