The uninterrupted shifting experience of the Shimano Dura-Ace R9200 12-speed cassette range lets you climb, sprint and push your limits without stopping to think about your next gear change. Larger driving cogs maximize drivetrain efficiency and create compatibility with both Shimano 11 and 12-speed freehub bodies.Super lightweight 12speed HG+ cassette with a rigid carbon and alloy carrier for excellent shifting even under the most demanding gear changesHyperglide+ sprockets have a computer designed tooth configuration with contoured shift gates, resulting in a crisp smooth shift even under loadClose ratio gearing allows a more efficient use of energy through finer cadence controlLargest sprockets are mounted on lightweight alloy and carbon carriers to reduce weight and increase rigidity5 largest sprockets are made from titanium to reduce weight without sacrificing strengthSprockets are extensively cut away and drilled to further reduce weight without reducing rigidityNickel-plated finish offers hard wearing resistance to corrosionAlloy cassette lock ringFor Super Narrow 12-speed chainsHyperglide+ 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.
Shimano Adaptor to connect electric wire SD300 to current SD50 wire system.EW-SD300 wires use a slim 3.45 mm diameter plug, they can be connected to the 5.1 mm EW-SD50 wires with the use of EW-AD305 adapterReliable and secure water resistant connection
The new Shimano EC300 charging connector is designed specifically for Shimano's 12-speed Di2 road drivetrains. Connected via the rear derailleur, it is also compatible with Shimano power meters. Charging of the new Shimano 12-speed Di2 road drivetrains is now accomplished with the EC300 charger cord. Attached to the rear derailleur, this new cord is less expensive than previous chargers and can also be used to charge Shimano power meters.Di2 charger cable for the internal battery that will keep your Di2 system shiftingDi2 uses a powerful long-life 7.4V Li-Ion battery: keep it in top condition and ready for shifting with this specific Shimano Di2 charger1.5 hour charge timePlugs in directly to RDR9250 rear derailleur
