Product Description
HYPERGLIDE+ cassettes have revolutionized off-road gear shifting with their smooth shifts in both upshift and downshift. Now it's time for the technology to change road cycling. Even during maximum efforts on a climb or near the finish line, cyclists no longer need to back off to make a shift. In any gear, DURA-ACE R9250 transmissions maximize efficiency thanks to the larger sprockets and maintain compatibility with existing 11-speed rear hub bodies. All this while increasing to 12 gears and without increasing weight, the DURA-ACE CS-R9200 cassettes are the new paradigm in road gear shifting.
