Shimano Dura Ace Hyperglide Cassette 12 Speed CS-R9200~11-30T andCS-R9200~11-34THYPERGLIDE+ 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
