HYPERGLIDE+ cassettes have revolutionized off-road shifting with their seamless shifts both up and down the gear range. Now it's time for the technology to change road cycling. Even during maximal efforts up a climb or nearing the finish line, riders no longer need to back off to perform a shift. In any gear, DURA-ACE R9250 drivetrains maximize efficiency thanks to larger cogs and retain 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.
