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).
