Tooth Count - the number of teeth on the chainring, the higher the number the harder the gear.

Between Adjacent Bolt Holes - the measurement from the centre of any bolt hole to the centre of an adjacent one, if this measurement is the same as that of your crankset and the bolt count is the same then the chainring should fit.

BCD - stands for Bolt Circle Diameter (sometimes referred to as PCD - Pitch Circle Diameter) and is the technical way to determine whether the chainring fits your crankset. To calculate, multiply the distance between adjacent holes (in mm) by 1.709 (you’ll likely need to round the resulting number up or down a little).

Bolt Count - the number of bolts securing the chainring to the chainset. As with the BCD, this must be the same as your chainset.

Chain Width - 3/32” is the standard width for double and triple chainsets, wherease 1/8” chainrings are only found on single ring chainsets, generally for track / singlespeed use and can only be used with a wide 1/8" chain.

Intended Speed - the number of cogs at the back the chainring 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 chainrings intended for 10 speed use or higher, with these it’s better to stick to the intended speed.

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.

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.
