Tooth count - the number of teeth on the chainring(s), the higher the number the harder the gear.
Chain width - some single chainsets will only work with a thicker 1/8” chain, all other chainsets take a standard 3/32” chain.
BCD - the distance between the chainring bolts, you’ll need this if you want to change rings.
Speed* - the number of cogs at the back the chainset was originally designed to be used with. You can happily mix different speeds, it’s just worth noting that the bigger the difference the more likely you are to experience shifting issues. As a rule of thumb, one or two speed difference shouldn’t be a problem, unless the chainset is for 10 speed or higher - these usually need the correct speed chain to avoid problems.
Pedal threads - this is usually stamped on the pedals. The standard thread is 9/16” x 20 tpi which almost all bikes use, the exception being older French bikes, bikes with one-piece cranks and Shimano’s Dyna Drive system - these are not interchangeable.
Bottom bracket type - ‘square taper’ bottom brackets, as the name suggests, have a square shaped axle that slots into the chainset. These are interchangeable between brands as long as you stick to the same axle length & profile. With all the other brand specific systems such as Shimano’s Octalink you must stick to the matching bottom bracket type.

Tooth Count - the number of teeth on the chainring, the higher the number the harder the gear.
Between Adjacent Bolt Holes - the measurement from the centre of any bolt hole to the centre of an adjacent one, if this measurement is the same as that of your crankset and the bolt count is the same then the chainring should fit.
BCD - stands for Bolt Circle Diameter (sometimes referred to as PCD - Pitch Circle Diameter) and is the technical way to determine whether the chainring fits your crankset. To calculate, multiply the distance between adjacent holes (in mm) by 1.709 (you’ll likely need to round the resulting number up or down a little).
Bolt Count - the number of bolts securing the chainring to the chainset. As with the BCD, this must be the same as your chainset.
Chain Width - 3/32” is the standard width for double and triple chainsets, wherease 1/8” chainrings are only found on single ring chainsets, generally for track / singlespeed use and can only be used with a wide 1/8" chain.
Intended Speed - the number of cogs at the back the chainring was designed to be used with. We refer to it as ‘intended’ speed as most double and triple chainsets will actually work with different speeds than originally intended, but the further away you get from the intended speed the more likely you are to experience minor setup issues. The exception being some chainrings intended for 10 speed use or higher, with these it’s better to stick to the intended speed.

Shifting system - friction means your gear levers don't click when you change gear, when they do click it's referred to as indexed shifting. If you have indexed gear levers they must use the same system as the rear derailleur, if you're using friction levers you can mix and match.
Speed - the number of cogs at the back the derailleur was designed to be used with. This is important with indexed shifting, but with friction shifters you can in theory run any rear mech with any number of cogs, but you are more likely to have issues running high numbers of cogs with mechs from earlier eras.
Max cog size - the amount of teeth on the largest cog of your freewheel/cassette can be no greater than this to work with this derailleur.
Chain wrap - subtract the size of your smallest rear cog from your biggest, then do the same with your chainrings, add the 2 numbers together and you have your chain wrap.
Chain width - generally speaking, derailleurs designed for more than 3 speed use will fit a standard 3/32'' chain, the exception being some Cyclo & Simplex models from around the mid 1900s.
