Two arms: a left timing ring arm (110 BCD, 5 bolt with 'hidden' bolt) which could be used for front or rear, and a right arm with no spider, which corresponds to a front/captain arm. This crankset is only compatible with a tandem (or a non-standard left-hand drive system). Square taper interface. Both arms are 170mm in length. Bolts, ring, and accessories not included.
If you need only one of the arms, please contact us to split the listing.
