Park Tool BBT-27.2 Tool Fitting Example

Count Splines/Notches

Remove the crank and inspect the bottom bracket shell for tool fittings, which can be notches or indentations on the outer perimeter, splines on the inside perimeter, or pin holes on the face. Count the number of tool fittings on the cup.

Measure Diameter

Next use a caliper to measure the diameter or width of the tool fittings. For external notches, simply measure the outer diameter of the bottom bracket cup or adapter. Take the measurement in millimeters.
