Made of aluminum and steel, the technology of this Octalink V2 system was overcomplicatingly simple. The set includes one bottom bracket and is specifically designed for a 109.5mm shell width. This bottom bracket was taken directly off of a 2005 Cannondale r3000si and includes everything that is shown in the detailed photos.
