e*thirteen cranks utilize a 30mm aluminum spindle to maximize spindle stiffness
  • e*thirteen cranks utilize a 30mm aluminum spindle to maximize spindle stiffness

  • It is important to note that even though our cranks use a 30mm diameter spindle they are not on the BB30 standard and will not drop in to a BB30 frame. Our cranks use a wider spindle that allows the to fit in a variety of frames and as such they require wider bearings seats than BB30 cranks.

  • As a result e*thirteen cranks use proprietary bottom brackets in order to accommodate the larger spindle

  • We offer our BBs in four different common configurations

  • BSA threaded

  • PF30

  • BB30

  • BB89.5/92/107/121/132 (aka pressfit 41mm)
