Shimano Dura-Ace CS-R9200 12V Cassette Sprocket

HYPERGLIDE+ cassettes revolutionized off-road shifting with seamless shifting and downshifting. The time for technological change has come for road cycling. Even during maximum efforts on climbs or near the finish line, riders no longer need to reduce pressure on the pedals to change gears. In every gear, DURA-ACE R9250 drivetrains maximize efficiency with larger sprockets while maintaining compatibility with existing 11-speed rear hub bodies. All this while going to 12 gears and without increasing weight, DURA-ACE CS-R9200 cassettes are the new frontier for road bikes.

Characteristics:

• Faster and smoother gear changes even under maximum pedaling loads
• The refined 12-step progressivity maximizes efficiency and acceleration performance for all situations.
• Adding wider 34D specs also for pro-race use
• Compatible with the new 12v rear hub body and 11v road hub body
