Shimano's Dura-Ace Track Cranks transform every last watt into oval-scorching speed in the velodrome. These cranks set the bar for low weight and unmatched efficiency, with hollow forged aluminum crank arms and an Octalink bottom bracket (sold separately) for power transfer and acceleration that will blow you, and those trying to hold your wheel, away.
