HYPERGLIDE+ cassettes revolutionized off-road shifting with their smooth uphill and downhill shifts. Now it’s time for technology to change road cycling. Even during maximum efforts on climbs or near the finish line, riders no longer need to slow down to make a shift. In every gear, DURA-ACE R9250 drivetrains maximize efficiency with larger sprockets while maintaining compatibility with existing 11-speed freehub bodies. All this while increasing to 12 gears and without increasing weight, DURA-ACE CS-R9200 cassettes are the new paradigm in road shifting.
