Nukeproof Warhead 44IISS TR Headset

Precision-engineered to the most exacting of tolerances to deliver optimum performance and long life in harsh riding conditions.

Answer: 
Not being a Specialized dealer I am unable to confirm, but if you remove the headset assembly from your frame and measure the internal diameter of your headtube, 41.8mm represents an Integrated Campagnolo headset such as the IS42 below, or if it is 44mm you will need a Semi-integrated system (such as this Nukeproof 44IISS), or 41mm requires the Cane Creek Integrated IS41 (also linked below).

Answer: 
I have tied to find a definitive answer for this but have failed, the only thing i can say is it is highly unlikely that this will fit your frame, as your 2004 specialized used a standard steerer and OS steerers were either Very rare or non existent back then so it is probably safe to say NO but measure the diameter of your head tube if it is smaller than 44mm you have you're answer
Sorry I could not be sure

Will this fit my new Ragley Piglet 2 frame?

Ragley recommend Nukeproof headsets, and they say 44IESS/44IISS will fit, but even within that narrow choice I'm not 100% sure which one I should get? Will any of them be fine, or do I need a specific one? I know it's a 44mm frame, and I have a 1 1/8" fork, but I'm still a little baffled by the differences between just the different Nukeproof headsets, l;et alone anything else :) I assume the stack height is personal taste, but cup depths and types (internal/external) I'm not sure about...

Answer: 
Yes; with a 44mm headtube on your frame any of the Warhead 44 headsets will be compatible.
The style depends on the fork steerer and travel; for a straight 1.1/8" fork up to 130mm of travel use the 44IESS, and for 140/150mm travel use the 44IISS (The -TR version uses shallower cup insertion so is compatible with more frames).
For a tapered steerer you would use 44IITS, and for a 1.5" steerer you would use 44EEOS.

Answer: 
Hi, bit of a minefield this headset business,
Basically either will fit,
THE main difference is the 44IISS will fit flush with the frame and the 44IESS will have an external bottom cup
i understand the lettering is intended to explain size and type of fit and steerer
IE 44 = mm diameter
II = internal/internal
SS= standard steerer (1 1/8)

IE= internal/external (top internal/bottom external)
OS= oversize steerer(1 1/2) TS =taper sterrer
EE=external external

Answer: 
Yes, the Snap runs a 44mm headtube so this will fit fine to run a straight 1.1/8" steerer (SS).
