Chainring Count - the number of chainrings on the chainset. Fixed gear track bikes, single-speeds and some geared bikes use a single chainring, road bikes commonly use a double (two rings) and most touring bikes and mountain bikes will use a triple chainset (three rings).
Tooth Count - the number of teeth on the chainring(s), the higher the number the harder the gear.
Bottom Bracket Type - ‘square taper’, as the name suggests have a square shaped axle that slots into the chainset and ‘cottered’ axles are round and secured by pins - pretty much every bike up until the 1990s would use one of these, cottered being the much earlier system. Since then, different manufacturers have introduced their own systems that are not interchangeable so you must use a chainset that matches.
BCD - stands for Bolt Circle Diameter (sometimes referred to as PCD - Pitch Circle Diameter) and is only really needed when changing chainrings. To calculate the BCD, measure the distance in millimeters from the centre of any chainring bolt to the centre of an adjacent one and multiply it by 1.709 (you’ll likely need to round the resulting number up or down a little to get your BCD measurement).
Crank Arm Length - this is measured from the absolute centre of the bottom bracket hole to the centre of the hole for the pedal.
Chain Width - this is mostly only relevant for chainsets with a single chainring - if this is ⅛” then you must use a ⅛” chain. Almost all double and triple (and some single) ring chainsets will use a standard 3/32” chain, the only exception being old chainsets designed for 3 or 4 speed freewheels.
Pedal Threads - this must match the thread of your pedals and is usually stamped on the pedals themselves, most bikes use a standard thread of 9/16” x 20 tpi. The exceptions being older French bikes, bikes with cheaper one-piece type chainsets and Shimano’s Dyna Drive system (easily identifiable as the pedal holes are about an inch wide!).
*Intended Speed - the number of cogs at the back the chainset 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 chainsets intended for 10 speed use or higher, with these it’s better to stick to the intended speed.
*Bike Type - this is just a guide, any chainset can technically be used on any bike as long as everything's compatible.

✓ Original part - produced in the 1980s
✓ Suitable for historic cycling events such as L'Eroica
✓ Professionally checked & cleaned

Campagnolo Victory chainset (or crankset, if you prefer), hailing from Italy and dating back to 1985.

Chainring Condition - Good

Chainring count - the number of chainrings on the chainset. Fixed gear track bikes, single-speeds and some geared bikes use a single chainring, road bikes commonly use a double (two rings) and most touring bikes and mountain bikes will use a triple chainset (three rings).
Tooth count - the number of teeth on the chainring(s), the higher the number the harder the gear.
Chain width - this is only relevant for chainsets with a single chainring - if this is ⅛” then you must use a ⅛” chain. All double and triple (and some single) ring chainsets will use a standard 3/32” chain.
BCD - stands for Bolt Circle Diameter (sometimes referred to as PCD - Pitch Circle Diameter) and is only really needed when changing chainrings. To calculate the BCD, measure the distance in millimeters from the centre of any chainring bolt to the centre of an adjacent one and multiply it by 1.709 (you’ll likely need to round the resulting number up or down a little to get your BCD measurement).
*Intended speed - the number of cogs at the back the chainset 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 chainsets intended for 10 speed use or higher, with these it’s better to stick to the intended speed.
Crank arm length - this is measured from the absolute centre of the bottom bracket hole to the centre of the hole for the pedal.
Pedal threads - the pattern of the thread that your pedals screw into, this is usually stamped on the pedals themselves and most bikes use a standard thread of 9/16” x 20 tpi. The exceptions being older French bikes, bikes with cheaper one-piece type chainsets and Shimano’s Dyna Drive system (easily identifiable as the pedal holes are about an inch wide!).
Bottom bracket type - ‘square taper’, as the name suggests have a square shaped axle that slots into the chainset and ‘cottered’ axles are round and secured by pins - pretty much every bike up until the 1990s would use one of these, cottered being the much earlier system. Since then, different manufacturers have introduced their own systems that are not interchangeable so you must use a chainset that matches.

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.
