2012 Shimano Ultegra FC-6750 10 speed Crankset (Silver)

Shimano FC-6750 Ultegra crankset resembles the Dura Ace 7950 series with a new hollow outer chainring for maximum stiffness and positive shifting under power. The new design also reduces incidence of the chain catching on the outer ring when in the smallest front ring and smallest rear cog. The change saves 15-grams over the Ultegra SL crank.
