A comprehensive guide to vintage gear ratios

2025-01-20T21:52:55Z

10.0.1.12 :

This will differ from a standard wiki pages as it more aims at being an introspect into some of the research I've done and compiling what I've learned through said research.

I'm only a newborn in the realm of cycling and even more in the realm of (vintage) road bikes. I specify vintage road bikes because I've always been interested in the value second-hand objects can offer and I therefore began my cycling journey with a bike several decades older than me. The first issue I ran into when mixing practice and usage of the road bicycle was that the ratio available to me was absolutely abysmal. My first bike was a Raleigh Equipe with a 1x drive train, 52t in the front and a 7 speed corncob freewheel. I don't live in the Alps but I could figure out very quickly what was wrong. I've come a long way since then but I still am after the marginal ratio gains I can make when building up a vintage road bike while still using period correct components.

I am going to try here to offer some guidance on this quest. I will also touch on the advantages of mixing and matching components, era and fields of bicycle components.

= The rules =

The rules are fairly simple : when building a bike from a specific era, at the moment of manufacture of his bike, only a limited amount of components would've been available. As to keep the spirit of a vintage bike build, this is the contraint we are pulling ourselves through to spark the search of marginal gains. Because, for me as a newcomer it wasn't so obvious, modern components blow old components out of the water if you want to make it easier to climb up anything. The standard chainring setup used to be 52-42, it's now more something like 50-34 and certain brands have been pushing for even smaller chainrings. Old components are a constraint of their own. And so we are trying to optimise said old components.

I will also limit this guide to indexed shifters, which essentually means I will only be talking about 7, 8, 9 and 10 speed groupsets. It might seem odd but going friction makes it significantly easier to tinker, I will talk about friction in my "Past the rules" section.

Disclaimer and almost hot-take : Triple chainring setups will, with no doubts but an aesthetic one or elitist one or gatekeepy one, void any issue or constraint posed in the preface.

Real disclaimer : I will assume a tyre size of 25mm for the gear development.

= Playing by the rules =

== Campagnolo ==

Campagnolo was very scarce about the information they give on compatibility or even on the specifications of their components. So information will be guessed off the parts available for the different groups.

Two things to note about Campagnolo is that they always used a 135 BCD standard over the Shimano 130 BCD. This went on until they went straight to 110 BCD and eventually a 4-branch based mixed BCD. The minimum chainring size for the 135 BCD is 39T (not very different from the 38T Shimano). Not only that but it's necessary to mention that Campagnolo has had a very "panache"-based line up of gear ratios, to not say they outright gatekept their components to "real" cyclists who didn't need small gear ratios for a very long time.

=== 7 speed ===

7 indexed speed Campagnolo is a convoluted mess as Campagnolo themselves suggested the use of different brands of freewheel and cassette. The 1987 Documentation of the 7-speed Record group says "The gear capacity, from 12 to 28, is the usual range for racing or fast touring" and a little later tells us the maximum cog size of the derailleur is 28T. So we will assume a minimum chainring size of 39T and a maximum cog size of 28T, making for a 1,39 gear ratio, or 2,94m of development.

=== 8 speed ===

This generation of vintage components is easily the most available, but the gear range available is quite small, with Campagnolo only going up to 26T in the back (on both a 13-26 and a 14-26 cassette) and 38T in the front, making for a 1,46 gear ratio, or 3,17m of development.

Curiously, and while I said previously that Campagnolo only offered cassettes up to 26T in the back, the Veloce, Mirage and Avanti derailleur are advertised as supporting up to a 28T maximum cog size, making for a 1,39 gear ratio, or 2,94m of development.

=== 9 speed ===

Campagnolo only ever produced up to a 13-28T cassette, making for a 1,39 gear ratio, or 2,94m of development.

Though once again, Campagnolo states all derailleurs except short cage Record and Chorus going up to a maximum cog size of 29T, making for a 1,34 gear ratio, or 2,84m of development.

=== 10 speed ===

Campagnolo finally caves in on the "Compact crankset" down the line of the 10-speed generation of Campagnolo components, offering a 34T smallest chainring option, but this time matching their cassette offering with the derailleur specifications they advertised, making for a 1,17 gear ratio, or 2,48m of development.

== Shimano ==

I want to quickly mention the Shimano 600EX (6207) and the Shimano 105 Golden Arrow (A105) groupsets which offered a long cage 6-speed derailleur that was advertised as being able to handle a 34T maximum cog size as far back as 1984. This would've made for a 1,11 gear ration. Far ahead of its time.

=== 7 speed ===

=== 8 speed ===

=== 9 speed ===

=== 10 speed ===

= Past the rules =

If what has been said until now is not enough, there are a few things we can mitigate to help further. Removing indexation removes the constraint of the number of speeds but most importantly allows us to swap over the MTB cassettes for exemple or ... Italian gods forbid, using a Shimano cassette on a Campy drive train. Mixing sub-groupset parts is another path you can go, using a Triple rear derailleur will also help accept bigger cog to chainring differences is the reason why, today, a 12s 105 groupset comes standard with a long cage rear derailleur, to accomodate for the 50-34 chainring setup coupled to the 10-34 cassette.

== Campagnolo ==

Miche offers more forgiving and even sometimes out of spec cassettes. For 8-speed and 9-speed, they match the 28T and 29T respective max cog size of the derailleur. For 10-speed, they go a bit further and offer a cassette going up to 30T. This makes for a 1,13 gear ratio, or 2,39m of development. This is as good as it gets without going for 11-speed.

== Shimano ==

As mentioned in the little preface, Shimano is very forgiving if you're willing to let go of perfect shifting, indexation and if you're willing to make use of components from their other fields of components. I am personally running ST-3400 with a 48/38 crankset, RD-M750 and a CS-HG201-9 (11-36) to get a maximum gear ratio of 1,08. The shifting is not perfect but it's also a botched drive train because I wanted indexation, I think I could have no issue with these components if I went with friction downtube shifters.

Shimano Dura-Ace Track

10.0.1.12 : /* Dura-Ace 7600 (1986-1994) */

In 1981 Shimano changed their nomenclature to better represent the components' name. They have done so before but the change from 1981 stuck and is still used as of today.
As such, I am going to try to squish identical groups with different names under the same category.

Campagnolo Record Pista

2024-08-06T19:31:19Z

10.0.1.12 :

This page about the Campagnolo Record Pista components was a little harder to make than the others.
Campa implied use of components from other groups to complete its Record Pista groups which made sometimes the Pista group poor in components and especially in comparison to Shimano's.
Also during the very short periods where Campa had two Pista groups, the differences between the two were generally very minor, creating a little confusion between the differences in the two groups.

Between 1988 and 2003, Campagnolo changed nomenclature twice and dropped or reintroduced at random some components from its Record Pista group, for exemple the Record Pista bottom bracket disappeared in the middle of the 90s because Campa used the same axle length as its Record Strada group. They didn't bother creating a new part number for ease of comprehension. Another exemple is the Super Record Pista 4100 group, it is centered around a crankset that is exactly the same (down to the part number!) as the Record Pista 1033, the only difference being a change in chainring design.

As such, I will deviate a little from the very "catalogue" approach you can see on the Shimano page to try and track the components that would've been used at the same point in time as the other Pista components of the same group.

I mention (1988-1993) but the group appeared in 1988 alongside the Record Pista A000P group and by 1993, only the latter remained.
This is an incredibly rare group so I haven't found many mentions of it, let alone parts and documentation. I will mention the placement of the NJS stamp on the parts I've actually seen in the wild.

In 1981 Shimano changed their nomenclature to better represent the components' name. They have done so before but the change from 1981 stuck and is still used as of today.
As such, I am going to try to squish identical groups with different names under the same category.

In 1981 Shimano changed their nomenclature to better represent the components' name. They have done so before but the change from 1981 stuck and is still used as of today.
As such, I am going to try to squish identical groups with different names under the same category.

The main hurdle to converting a road bike to a single sprocket bicycle (fixed gear or single freewheel) is to get the correct chain line. While many simply put their main chainring on the innermost placement of their double chainring and call it good enough, chainline is something that can be calculated and the aforementioned practice can be avoided. The issue about chainline is the fact that it's quite an abstract concept considering it's a fixed dimension that depends on two variable dimensions. Manufacturers don't make it easier because they usually tell both dimensions determine the chainline. For exemple, you will find the chainline in the specifications of either Bottom Brackets or Cranks depending on manufacturer, crankset, bottom bracket and even then, there is no real standard to how a chainline works and what it depends on. In this article, we're going to theorise the length of the bottom bracket needed to turn a double crankset into a single chainring crankset. We will focus on square axle bottom brackets as they are the most common type of BB used in conversions.

= Theory =

== What are chainlines ? ==

The basic gist of a chainline is that it is the straight line from the crankset to the back sprockets. There are multiple chainlines because there are different use cases and different cranksets. Chainlines make for a starting point for the chain to pivot from on a multiple sprocket bike. It is meant to be a "middle-ground" amidst all possible combinations of gears and chainrings.

But first, let's try to define what we aim for : a single chainring chainline. The single chainring chainline is the distance between the middle of your chainring and the plane that cuts your bike in half from one end to the other or to put it in a more telling way, the middle of your seat tube. It is meant to be as straight as possible from the chainring to the sprocket as these two points are the only possible positions.

The most common Single Chainring chainline is 42,5mm.

Now let's try to define what we're starting from : a double chainring chainline. The double chainring chainline is the distance between the middle of the space between your two chainrings and the same plane as before. Where it deviates in definition to the Single Chainring chainline is that there are two pivot points in a double chainring drivetrain. The chainline serves the same purpose : a middle-ground, but as the chain is a flexible component and as there are multiple sprockets, the double chainring system allows for multiple positions. Even in the optimal use cases, the line from the chainring to the chosen sprocket may not be straight. In fact, you can deviate from the recommended chainline and still keep a perfectly fine drivetrain.

The most common Double Chainring chainline is 43,5mm. It is the Shimano standard.

== How are chainlines ? ==

Chainlines are physically defined by the drive-side length of the axle from the middle of axle (same plane mentioned before) and where the chainring is situated on the crank, whether the crank forms a more or less concave element. Which is why different cranksets can require bottom brackets of different lengths while keeping the same chainline.

As bottom brackets come in many different lengths, we can shorten the required length of the bottom bracket from a double chainring crankset to account for the difference in the concave-ness between a single-chainring crank and a double-chainring crank and therefore give a double-chainring crank a single-chainring chainline.

== Where to start from ? ==

The start of the journey to theorise this entreprise is a double chainring crankset being used a single chainring crankset, with all specifications mentioned.
In this case, we're going to take the case of the Stronglight 107 crankset, according to the 1984 Stronglight No. 27 catalogue :
