Shimano's commitment to making the very best products to perform at the highest level continues with the Dura-Ace 7900 Hollowtech II crankset. The most notable improvements for this season are the use of a hollow outer chain ring which provides extra weight savings, increases strength and 20% more durability, a new tooth design for better ramping and chain contact on shifting, and an aluminum/carbon composite axle. For use with the Dura-Ace 7900 chain.
