Tacx T4025 jockey wheels (or derailleur pulleys if you prefer), hailing from The Netherlands and in production from the 1990s to the 2000s (yet still new & unused after all this time). Made from plastic and weighing in at 38 grams. A fine choice for keeping your classic bike authentic, but also great for any other compatible bike.
OVERVIEW
TECHNICAL INFO
Teeth - the tooth count has increased with the introduction of more gears, but this happened very gradually so 10 tooth jockey wheels were standard for a very long time.
*Compatible Speed - the number of cogs the jockey wheels were designed to be used with. When using derailleurs for indexed shifting it's important to stick to this, but friction shifting is much more forgiving so you're unlikely to have any problems using the next speed up or down, providing all the measurements are correct.
Diameter (OD) - the diameter of the jockey wheels, from the outside edge of the teeth. It’s important to stay close to the ones you're replacing to ensure they fit.
Thickness - measured at the widest point, by the centre hole. The spacing has generally become narrower over the years to accommodate more gears.
Centre Hole (ID) - the inside diameter (usually inside the bushing/spacer if present). This rarely presents a problem, but some older jockey wheels have a different diameter so it's worth double checking.

Campagnolo Super Record rear derailleur (or mech if you prefer), hailing from Italy and dating back to 1977. Made from aluminium/steel/titanium and weighing in at 180 grams - incredibly 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.
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 very good condition, but do take a good look at the detailed photos so you can see the cosmetic condition before you buy.OVERVIEW
TECHNICAL INFO
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.

Huret Duopar rear derailleur (or mech if you prefer), hailing from France and in production from the 1970s to the 1980s. Made from titanium/aluminium/ steel and weighing in at 256 grams. A fine choice for keeping your vintage bike authentic, but also great for any other compatible bike.
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 excellent condition, but do take a good look at the detailed photos so you can see the cosmetic condition before you buy.OVERVIEW

Shimano Dura-Ace freewheel, hailing from Japan and dating back to 1987. Made from steel and weighing in at 334 grams. A fine choice for keeping your vintage bike authentic, but also great for any other compatible bike.
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 freewheel!
The freewheel's been carefully cleaned, thoroughly checked by one of our mechanics and graded as very good condition, but do take a good look at the detailed photos so you can see the cosmetic condition before you buy, and please consider that freewheels wear with chains, so used freewheels can occasionally skip when partnered with new (and some used) chains. This can usually be avoided by using a compatible used chain of similar age, but there is no way for us to confirm which chain will work with which freewheel.OVERVIEW
TECHNICAL INFO
Speed - the number of cogs on the freewheel.
Range - the number of teeth on the smalles and largest cogs, this gives you an indication of how hard or easy the gearing will be, the lower the number the harder the gears. The tooth count of the cogs inbetween are usually evenly spaced, ie: a 6 speed 14-24 freewheel would likely have cog sizes 14, 16, 18, 20, 22 & 24.
Threading - this needs to match the thread of your rear hub. ISO is the modern standard and is almost exactly the same as older English/British and Italian thread, allowing you to mix and match between these thread types as long as it's not going to be under extreme force, in which case it's best to stick to an exact match. Hubs with a French thread must be used with a French threaded freewheel.
Stack Height - the total height (or width if you're looking at it when installed) that the freewheel will require once installed, including any protruding body parts such as base plates.
Overall Sprocket Spacing - this is measured from the outside of the first cog to the outside of the last cog.
Chain Width - this is mainly relevant for singlespeed and some older 3 or 4 speed freewheels - if this is ⅛” then you must use a ⅛” chain, but most freewheels (especially multiple speed ones) will use a standard 3/32” chain.

Campagnolo Nuovo/Super Record down tube shifters (or gear levers if you prefer), hailing from Italy and in production during the 1970s. Made from aluminium/steel and weighing in at 69 grams. A fine choice for keeping your vintage bike authentic, but also great for any other compatible bike.
If you're taking part in L'Eroica or a similar vintage event, these are fully compliant - so rest assured, the pre-1987 police won't lock you up for having the wrong shifters!
The shifters have 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.OVERVIEW
TECHNICAL INFO
Fixing Type - if you have small mounts on either side of the frame’s down tube you need braze-on shifters, if there are no mounts you’ll need clamp-on (sometimes referred to as band-on). Some 'aero' frames have mounts fixed to the top of the down tube, for these frames you require top mount shifters for the correct boss type (see below). There are also 'Clamp-Over' shifters that allow front & rear shifters to be used on a frame that only has a single braze-on.
Shift Type - friction shifters don't click into gear when you change, when they do click it's referred to as indexed shifting. For this to work correctly you must use the same system as your rear derailleur, if you're using friction levers you can mix and match. You don't need to worry about the front derailleur as left downtube shifters aren't indexed.
Speed - the number of cogs at the back the right shifter is designed to be used with. This is important with indexed shifting but with friction shifters you can in theory run any shifters with any speed setup, although the right lever will need to be pulled back further to shift into the larger cogs.
Shifter Boss Type - the shape of the mount (for braze-on fixings only). Campagnolo / ISO is standard and easily identified by the flat sections on either side, usually combined with a square base for the backing stop plates to fit. There are also Shimano ones with a keyhole shaped base and much less common French ones that are round with no flat sections.
Boss Thread Size - M5 (5 mm) is standard for Campagnolo / ISO bosses, but Shimano bosses will often have M4.5 (4.5 mm) threads and the French bosses would likely have 5 x 1 mm threads.

Simplex Silver Range down tube shifters (or gear levers if you prefer), hailing from France and in production during the 1980s. Made from aluminium/steel and weighing in at 110 grams. A fine choice for keeping your vintage bike authentic, but also great for any other compatible bike.

Regina Extra CX-S chain, hailing from Italy and in production during the 1980s. Made from steel and weighing in at 300 grams. A fine choice for keeping your vintage bike authentic, but also great for any other compatible bike.
If you're taking part in L'Eroica, Anjou Velo, Velo Retro or another similar vintage cycling event, this is fully compliant - so rest assured, the pre-1987 police won't lock you up for having the wrong chain!
The chain's been examined for wear, thoroughly cleaned and degreased, then freshly lubricated and graded as very good condition, but do take a good look at the detailed photos so you can see the cosmetic condition before you buy. Chain stretch for this one comes in at 1/64” (around 15% worn), measured by hand as this is the most accurate method, and although it’s impossible to be exact it gives a good indication of how much use a chain has had.OVERVIEW
TECHNICAL INFO
Optimal Speed - the ideal number of rear cogs, based on the outer width of the chain and the cog width it was designed for. For 6 Speed Shimano Uniglide a 5/6 spd chain will perform best.
Shifting System(s) - indexed shifters 'click' when you change gear. For 9 speed upwards (or Suntour Accushift), to guarantee the best performance we recommend using the dedicated chain. Otherwise, for 8 speed and below, or any speed when using friction shifting (non-index), you just need the correct outer width.
Outer width - measured across the rivets at the widest point, these are the approximate widths for different speed setups (up to 4 speed is also dependent on cog width):
| Speed | Outer Width |
|---|---|
| 2 to 4 Speed (1/8”) | 8.5 to 9.5 mm |
| Up to 6 Speed (3/32”) | 7.8 to 8.0 mm |
| 7 Speed / ‘Narrow’ 6 Speed | 7.3 mm |
| 8 Speed / ‘Narrow’ 7 Speed | 7.0 to 7.3 mm |
| 9 Speed | 6.5 to 6.7 mm |
Cog Width - the gap between the inner plates allows for different rear cog/sprocket widths. 3/32" is the standard for 5 to 8 speed, above that it’s 11/128”. For 4 speed or less, 3/32” and 1/8” were both used, for the latter you will need a 1/8” chain. A wider 3/16" moped chain can be used as a heavy duty opton for single cog setups if required).
Chain pitch - the distance between the rivets/pins. All chains will be 1/2" with two exceptions; 3/16" (“inch pitch”) for very early track bikes, or Shimano's short lived 10 mm pitch system from the 70s/80s.
Number of links - if you're unsure how many you need, measure your old chain (each link has two rivets) or one with a similar setup to yours.
