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.

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.

Generally Speaking, you only need to worry about freewheel threading if it's French. Modern (Standard ISO) & older British Or Italian freewheel threads are interchangeable in most cases. The only real exception being if you are applying extreme force (very large/strong riders or tandems)
We only sell freewheels with plenty of life left in them. We measure the stack height of each freewheel to determine if your frame has enough space for the specific freewheel.

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.
