Quality And Value
Our 40-Series headset is the entry point for performance, quality, and value. Drawing from the premium 110-Series design, the 40-Series includes all the features necessary for a durable, lightweight, and easy to use headset.
Highlights:
We make headsets easier. Our headsets use interchangeable parts and over forty configurations to meet almost every size need. Sold in straight and tapered assemblies or tops & bottoms, tops are generally available in either short (9mm) or tall (15mm) bearing covers to further customize the look of your cockpit setup.
Featuring a full alloy construction – sealed cartridge bearings, 6000 series alloy cups and materials, and a sealed steel crown race, the Forty series headset sets the standard for all other headsets to be judged.
The ZN40 bearings are corrosion-resistant zinc-coated, machined steel cartridge bearings with hardened steel balls, which vastly increases the longevity of the 40 series headsets.
Our patented Interlok spacer design provides solid interface between the top cover and spacer stack, meaning they “nest” together and into the top of the bearing cover, which helps minimize shifting under load while riding; and shave 25% in weight off a standard alloy spacer stack. Spacers sold separately
In 1992, we brought the Aheadset®, the original threadless headset, to market – kicking off a major change in the way bicycle frames and forks would be developed going forward.
The original design of that revolutionary headset is still found in almost all bikes on the market today.

I'm not sure which product you are referring to but if you are asking about the 40 Series headsets, yes these will fit on your Luna Talaria. I am not sure what size headset you need as Luna does not offer this information. You can try to call them, or take it to the dealer you purchased the bike from and they can help you size the headset.
If using a straight 1-1/8" fork you need the 52/30mm crown race. Part number: BAA0009S
I could not find any information on the GT Grade other than its listed as using "integrated TH sealed cartridge bearings". This means it is an integrated headset so likely using either 41mm bearings, or 42mm bearings. Both are common in integrated headsets...I suggest going to your local bike shop and they can measure your bearings and make sure you order the correct ones. We have the correct bearings, but without measuring I cannot tell you which size you need.
That is correct. Your 2022 Rockhopper uses a 44mm internal diameter (ID) head tube. To use a tapered fork you will need to replace just the lower headset with an EC44/40 headset.
Your 2012 Chameleon uses a 34mm ID (inner diameter) head tube. To use a tapered fork, you need a minimum 44mm ID head tube. Unfortunately you cannot use a tapered fork on your Chameleon.
