Dura-Ace C50 Tubeless Disc Rear
The all-rounder of the new DURA-ACE wheel lineup, the C50 is both lighter than the previous C40 model and nearly as aerodynamic as the previous C60. It's a wheelset at home in a wide range of conditions. From time trials to criteriums, on rolling terrain or attempting a personal best, the new C50 is the ideal wheel for spirited road riding.
The perfect blend of low weight and aerodynamic performance, the all-new DURA-ACE C50 features an updated all-carbon tubeless rim and new hub design that drops weight while enhancing rigidity.
- 50 mm height full carbon rim
- Internal rim width: 21 mm
- DIRECT ENGAGEMENT
- Compatible only with Shimano road 12-speed cassette sprockets
