Cotterless, Three-Piece Chainrings
Three-piece cranks, or Cotterless cranks, have two crank arms pressed and bolted to the crank axle, hence three pieces.
Chainrings are usually interchangeable in this format, offering more options for touring and racing cyclists.
Interchangeable rings are bolted onto the crank arm's spider arms, like a spider or tentacles of a star fish,
with chainring bolts and, if necessary, chainring bolt spacers.
There are three-, four-, five-, and six-spider arms, with many sizes of chainring bolt circle diameter (bcd).
