Shimano has announced the launch of its all-new Dura-Ace wheel lineup, a next-generation aerodynamic wheel range developed to deliver race-ready speed, efficiency, and ride quality through a series of advanced re-engineered structures. Lighter, faster, and engineered for modern racing in collaboration with professional triathletes including Kat Matthews and WorldTour riders from Alpecin Deceuninck and Fenix Deceuninck, including Mathieu van der Poel, the new DURA-ACE wheel lineup is built for riders seeking maximum speed and responsiveness. Here’s how the new DURA-ACE wheels compared with the previous R9270 generation:Most triathletes remember when 21 or 23mm tires were the norm. Rather than taking a one-size-fits-all approach, Shimano tailored the spoke type, count, and configuration for each wheel in the lineup.
