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 crank was designed to fit. 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).
BCD - stands for Bolt Circle Diameter (sometimes referred to as PCD - Pitch Circle Diameter), and this needs to match the BCD of your chainring(s). To calculate this, measure the distance in millimeters from the centre of any chainring bolt hole 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.
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 crank 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 crank that matches.

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).

Crank Bolt Type - 15 mm hex bolts used to be standard but some older TA, Stronglight and Zeus cranks used a larger 16 mm bolt, plus a few Japanese makers used a smaller 14 mm hex head. Allen key types were introduced in the 1980s and some are self-extracting, which means the crank removes itself when you undo the bolts.
Crank Bolt Thread - All square taper bottom brackets have a standard M8 x 1 mm thread, the only different thread types you’ll find on crank bolts are the much larger M12 & M15 bolts that are specifically for Octalink and ISIS bottom brackets.

Pedal Type - this is just a guide to give you an idea of the pedal type, but any pedal can technically be used for any purpose. Track pedals are designed without the pointed 'quill' for safety though, so it's best to only use track pedals for this purpose. Most track pedals, along with quill & aero road pedals are designed to be used with toe clips & straps for best performance.
Pedal Threads - this must match the thread on your cranks. Sometimes it's stamped on the end of the crank arm, but 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!).

Clamp Opening - the minimum and maximum distance between the inside of the nut and bolt heads. The minimum is measured with the bolt tightened as much as possible (for hex head types this may mean the bolt end will stick quite far out of the nut). For the maximum opening we ensure 5-6 mm of thread remainis in the nut for a secure fixing.
Outer Diameter - the part that goes through the frame, most steel frames will take an 8 mm bolt whereas early lugged aluminium frames often have a larger hole that takes a 10 mm bolt diameter.
Bolt Fixing Type - Some binder bolts have knurled parts that grip the inside of the bolt hole, some have a small notch locator (a "key" that lines up with a cut-out in the frame if yours has one), others have tightening mechanism on both the nut and bolt to secure the seatpost in the frame.
