Shimano's model 7710 track crank has hollow arms and the Octalink V1splined bottom bracket attachment as used in the Dura-Ace 9speed road crank. However, the track arms are Keirin certified (NJS) and somewhat more robust than their road counterpart.

The cranks are available in 165, 167.5, 170, 172.5 and 175 mm. lengths, with a wide variety of chainring (144 bolt circle pattern) size options in both 1/8" and 3/32" formats.
