Headset Type - the 1" size relates to the outside diameter of your fork's steerer column which should measure 25.4 mm, if it's 25.0 mm your forks should be French threaded. Although it's generally recommended to match threaded parts exactly, with headsets you can technically mix and match, unless you have French or the obscure old Raleigh threads, in which case you need to stick to that type. If you're replacing an old headset the thread may be stamped on there. Oversized 1 1/8" & 1 1/4" sizes are easily identifiable due to their size and the threads are all standard. Headclip headsets were made to fit fork steerers with 1" or the reduced 31/32" size steerers, as well as 1 1/8" versions for tandems.

Cup Size (OD) - the outside diameter of the cups, this must match the inside diameter of your frame's headtube closely for a good fit. For 1" headsets this should be around 30.2 mm unless you require a JIS headset which will be 30.0 mm.

Crown Race (ID) - the inside diameter of the crown race where it sits on the fork steerer, this needs to be close to the outside diameter of your fork steerer at the base to ensure a proper fit.

Stack Height - the overall height of the headset. To check the minimum stack height you require, measure the length of your frame’s head tube & subtract this from the length of the fork steerer column. You can always add spacers if you have a little too much steerer tube but you can't fit a headset with a greater stack height than the space you have available.

Chainset Type - the number of chainrings the derailleur was designed to work with. ‘Double’ derailleurs are actually capable of working on ‘triple’ chainsets but they may struggle when shifting, especially if there’s a big step down from the middle to inner ring, so it’s better to match these correctly.

Frame Fixing - the way the derailleur fixes to the frame, if you have a tab on your frame to mount the derailleur to you need braze-on. If there’s no tab then you require a clamp-on type (also referred to as band-on or clip-on), these come in different sizes to match the diameter of your seat tube.

Pull Type - the direction of which the cable needs to ‘pull’ the mech in order to shift. If your cable runs up to the derailleur from the bottom bracket area then you need bottom pull, if your cable comes down from above you need top pull. Some later derailleurs can be used for either setups, these are referred to as dual pull.

Designated Speed (9 Speed & Above) - the speed of the chain that the mech was designed to be used with. This only becomes relevant for mechs marketed as 9 speed or above when chains became narrower, as the derailleur cage plates became marginally narrower too. We refer to it as ‘designated’ speed as technically you can use (almost) any derailleur with any chain, however if you want optimum performance it’s best to stay close to the manufacturers recommendations.

Indexing System (Shimano Only) - this is only applicable when using Shimano shifters that have an indexed left shifter such as STI or Rapidfire. For the indexing to work correctly when using these shifters the derailleur and shifters must be of the same type, so Shimano drop bar shifters need to be matched with a Shimano ‘road’ derailleur, and Shimano flat bar shifters must be used with Shimano ‘MTB’ derailleurs.
