Zero-stack tapered headset?

I have taken delivery of my new 2011 five with tapered head tube but have come up against an unexpected glitch. I have just discovered that the new bike uses a zero-stack headset. I have a tapered steer tube fork and am looking for a zero stack headset for 1.125" to 1.5" tapered forks – but they don't seem to exist???

Any ideas where to get one?

Eh?

Orange make a bike that you can't get a headset for?

I was surprised when I measured it too. Internal diameter of the head-tube is 44mm upper and 55.9mm lower (zero stack standards).

The stock bikes with tapered head tubes come with cane creek ZST25 headsets, but I can't find a stockist for them.

Had a similar problem with my Blur (mixed tapered), Cane Creek or Chris King were the only option

According to the Orange site they use a Cane creek zst25 tapered on a factory orange five. I can't find it for sale anywhere so your only option might be Chris King.

Unfortunately, Chris King don't do zero stack headsets. In fact they have a bit of a rant about it … here

Why does it have to be zero stack? Would a normal lower race and then a zero stack top race work? Various Cane Creek headsets are available in individual races now. You can definitely buy their Double XX headset as a lower race only.

I don't know if that would work. I think you need both upper and lower cups to be designed to zero-stack specifications.

Do you know where you can get a Double XX lower race?

My Bad..

Give Orange a ring they are normally very helpful and might be able to supply the Cane Creek. Alternatively you could try hope, you can get a Hope ZS tapered as an option on the bikes. Hope list all sort of integral/ntegrated/combi headsets.

Just had a quick look on the CK webiste, are you sure it's not Inset?

Well spotted! Didn't notice that. Good old hope to the rescue again. 🙂

Otherwise its a call to Orange.

Cheers. 🙂

The King inset 1.5 lower 1.1/8 top then a king adapter for the lower if you don't have a tapered fork steerer. It will cost you loads though.

If you find you can use a normal cup lower and inset top then this will be fine and is considerably cheaper

I think that's the same headsets as used in Trek bikes.

You should be able to order a cane creek one from a trek dealer- they're about £65, although cheaper bikes get cheaper models.

If you go to page 25 of this tech doc from FSA, headset number 57 or the Orbit 1.5ZS 1 1/8-1.5" is what you need. Again, this should be available from a Trek dealer as a spare part and will be a bit less than the Cane Creek one.

You can't put a normal lower cup in there, so the FSA one is what you need.

Hope do a zero stack tapered headset

Cheers for the suggestions. It seems that Hope, FSA, Cane Creek, and Chris King all do appropriate headsets, although finding them is a bit harder at the moment.

I already have a Hope 1.125" zero-stack/internal headset so I may phone them up and ask if they can provide me a lower cup, bearing, and crown race for a 1.5" fork.

Hi,
I have a zero stack FSA ZS-3 headset for tapered forks and needs a zerostack headset for non-tapered forks. Any chance of a trade??

Cheers,
Dave

Sorry Dave, got my Chris King inset yesterday.

… on the other hand, if you want to make me an offer for a Hope zero-stack headset. 🙂

Well if you've got a Chris King so you must be doing alright??? 🙂

I just bought a brand new hope headset for £35 – I have it currently advertised in classifieds as I now realise it was the wrong one. So assuming this one is used then I could offer you £25 depending on condition?????

Just to check yours is the 44mm semi-integrated one right…argghhh

Not so much doing alright, just too impatient to get my new bike going with minimum faff. 🙂

The condition is that it has been pre-fitted (obviously) but is in mint condition. It is on my XC hardtail which dosn't get ridden much any more so it hasn't taken too much use. I need to remove it first, but thats not a problem as I am friendly with the LBS.

Yep, 44mm diameter. Looks like this…

How does £30 posted sound? Can take it out this weekend and post some photos if you would prefer though.

Sounds good – do you want to email me 'dredding **at* sfu *dot*** ca' rather than keep on checking the forum??

Cheers,
Dave
