I've recently acquired a titanium mountain bike frame and I'm starting to shop around for bits to do a self build. I'm looking at headsets now, and I'm struggling to understand the plethora of terminology and metric/imperial measurements on various sites.

The frame is a 2009 Titus Fireline Titanium (26er), USA made, before Titus became one of the On-One brand. I assume therefore that the key measurements to look for are in inches.

The pictures below show the steerer tube:









I know the headsets are a pressed-in friction fit, is that what you would expect to see for a 1.5 inch steerer tube? Do I therefore need to search for a 1.5 inch 'internal' or 'integral' headset (the terminology seems to differ between brands).

For example, Hope use the terminology '1.5 inch integral':
http://www.wiggle.co.uk/hope-pick-and-mix-headsets...

Chris King seems to use the terminology NoThreadset, giving it the name of a 1.5 inch headset (35mm) but then going on to say in the product description that it suits a 1.5 inch fork steerer tube and a 49mm internal diameter frame, so that's too big for what I've got:
http://www.wiggle.co.uk/chris-king-nothreadset-15-...

Then there's this Chris King headset, another NoThreadset name, but with a 1 1/8 inch measurement, which I think it too small for my frame?
http://www.wiggle.co.uk/chris-king-no-threadset-1-...

Then we have Cane Creek, their 10 series is a 1.5 inch headset but their sizing chart says that's suitable for a 34mm internal diameter steerer tube (which is what I have):
http://www.wiggle.co.uk/cane-creek-10-series-tradi...

My issue seems to be the measurements reflect different things. They say a 1.5 inch headset is suitable for a 34mm frame, but 1.5 inches isn't 34mm. It's more like 39mm....

Can someone help explain? Or just point me to some links for Hope/Chris King/Cane Creek that will fit my frame shown?

Cheers!

Iain

I would suggest you allow your Local Bike Shop to sort this one out

You will need the forks and frame to sort out the sizes to match up.

Let the shop know the quality you would like and let them do the rest, then if there is a problem it is theirs to sort out as you have found out there is a minefield of sizes out there for MTB's

Once you have a headset you van order a spare or the next one from the one fitted (ask for the box)

MTB's are probably worse than road frames but there are heading in the same direction with special sized bearings.

I'd say it's a pretty standard 1 1/8th headset. 1 1/2 is something you'd usually see on a oversized alloy or CF frame.

I could be wrong though so i think you'd be best to go down to your local bike shop and let them get the right headset for you. Even if you let them install a cheapo one so you can then order a bling one safe in the knowledge that you're going to order the right size.

Apologies for the hijack but I have a vaguely relevant question.

Presuming that the diameter is the same is one crown race the same as another? I have some forks that I will ultimately swap onto another frame, I can’t find the same headset for sale that I had fitted which is where the current crown race came from. Would the one I have work with other brands of Aheadset on the next frame I get?

Thanks in advance

To give this thread a bit of closure, after all my faffing about ordering the wrong headset initially, it turns out it's just a standard 1 1/8th headset. This is me pressing in the Hope headset using my home-made press constructed from some M12 threaded bar and associated washers, turned out rather well:

nice press, a legitimate one is basically the exact same thing anyway

glad you got it sorted
