Shimano Dura-Ace Di2 R9200 Groupset Builder

The DURA-ACE FC-R9200-P power meter brings everything a data-driven cyclist could want. Its integrated, waterproof design brings all-weather reliability while delivering accurate information including left/right balance. A rechargeable Li-ion battery is user-friendly and Bluetooth LE and ANT+ connectivity ensure easy setup.

The fastest just got faster thanks to the DURA-ACE FD-R9250. Tipping the scales under 100 grams, the new design shifts 45% quicker than Shimano's FD-R9150, already the fastest on the market. The frontal area of the FD-R9250 is also reduced decreasing aerodynamic drag.

Shimano HYPERGLIDE+ cassettes have revolutionized offroad 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.

The DURA-ACE RD-R9250 integrates the system charging port and a wireless connectivity unit all while delivering super fast, precise shifting worthy of any podium. A single cage length shifts cassettes from 11-28 to 11-34 bringing new versatility to the world's best road component group.
