Extension Length (ctc)* - we measure from the centre of the handlebar clamp to the centre of the shaft, to the point where the stem bolt passes through, to the nearest 5 mm. We always take this measurement in a straight line through middle of the extension, not along the top. In some cases the stem may be stamped with a different extension length as some manufacturers measured differently, but we always use our own measurement for consitency.
Quill Size - the most common size for classic and vintage road bikes is 1", this should be the same as the outside diameter of your fork's steerer column. Oversized steerers found on mountain bikes and later road bikes will be either 1 1/8" or 1 1/4".
Steerer Size (ID) - this is the most important measurement when checking the stem fits your bike. This should match the measurement of the inside of your fork's steerer column, where the stem will be inserted. The standard size for road quill stems was 22.2 mm, or 22.0 mm in France until the 1980s.
Total Shaft Height - measured from the top where the expander bolt head sits, to the bottom of the stem's shaft. To give you an idea of how high the stem can be set, there should be an absolute minimum of 50 mm inserted into the fork steerer, although most stems come with a 'minimum insertion line' to help with this.
Clamp Size - this should match the outside diameter of your handlebars and should be as close as possible to ensure a good and safe fit.

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.

Chainring Count - the number of chainrings the bolts are designed to fit, this must be the same as the number of chainrings you are using.
Crank Type - Most cranks require the standard 5-bolt sets that consist of 5 bolts with backs that slot into the rear of the crank spider, there are also some less common cranks with 3 arms that require the 3-arm chainring bolts. Specialites T.A. 'Professionel 5 Vis' and Stronglight '49D' type cranks require special 50.4 BCD chainring bolts that are specific to these crank designs.
Mount Type - most bolts simply fix the chainring to the crank, but some cranks require bolts to fix one chainring to another.
Back Nut Length (Excluding Head) - the more chainrings your crank has the longer the bolts and nuts need to be. We exclude the head part from the measurement (the bit that often sits recessed in back of the chainring).
