Includes 1x left bottom bracket cup.

See below for lengths measured from end to end. Many are confused what size is needed. Keep in mind anytime a bottom bracket cup size is changed, a spindle is also necessary to match among other items like a motor hanger and side bracket depending on fit. Contact us when in doubt prior to purchasing so we can properly advise you.
