Zeus Criterium rear mech, hailing from Spain and in production from the 1960s to the 1970s. Made from steel/aluminium and weighing in at 213 grams - pretty lightweight for a rear derailleur at that time. A fine choice for keeping your vintage bike authentic, but also great for any other compatible bike too.

If you're taking part in L'Eroica or a similar vintage event, this is fully compliant - so rest assured, the pre-1987 police won't lock you up for having the wrong rear mech!

The mech's been carefully cleaned, thoroughly checked by one of our mechanics and graded as good condition, but do take a good look at the detailed photos so you can see the cosmetic condition before you buy.

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.
