Crank arms, chainrings and the bottom bracket they need. Campagnolo Record Strada cranks use a 144 mm bolt circle (inner ring 41 teeth or larger) and 8-speed Chorus 135 mm; Shimano and later SunTour road doubles use 130 mm. Bottom bracket threading (English, Italian, French or Swiss) and spindle length have to match the frame and the crank.
