Description
To get cyclists and mechanics started with the updated and redesigned Di2 shifting system for the Dura-Ace R9200-series 12-speed components, Excel Sports is offering this special component kit package for faster, easier purchase. You get the key Di2-related components and essentials that are required for a frame build with hydraulic disc braking. We have also included the new Battery, charging cable, a 12-Speed chain, and your choice of the R9200 cassette options (11-3T or 11-34T). Given the challenge of sourcing Dura-Ace components, we are assembling these kits as items become available. Please know that some kits will come with the Shimano-boxed Lever with Caliper, while others may come with individually packaged lever, caliper, and hydraulic hose kit items. Other components that have options specific to a frame/rider/set-up are offered separately.
The R9200 series is only available in the new Di2 system, and won't be offered for mechanical shifting. Shimano is referring to this as "wired-less", as the shift levers powered by coin cell style batteries, while an internal seatpost mounted battery is wired to the front and rear derailleurs. This eliminates complicated E-Tube wire routing in today's fully integrated cockpit bikes and keeps the system in premium efficiency all around. Shimano calls the R9200 series the "Science of Speed", as every detail, every decision, and every component of the R9200 series is engineered to deliver a faster, more reliable, and more intuitive ride experience. Shimano dedicated years of research, development, and testing to refine its this flagship road system.
The new shifting system delivers 58% faster rear shifting and 45% faster front shifting compared to the wired R9100 Di2. The Di2 lever switches are also redesigned for better control and easier access. The longer switches are easier to reach, and an increased offset between the switches makes them easier to differentiate while riding. A third, accessory switch on the top of each hood carries forward. The shifter bodies are 4.6mm longer for better hand position and safe control. Ergonomics of the upright section and the overall design itself are now even better, with a natural feel and more purchase area. The hydraulic brake system now features Shimano’s proven SERVO WAVE technology to enhance performance thanks to a faster initial bite point followed by a wider control area. This allows riders to modulate their braking forces more easily, with precision. The update delivers a quieter braking system. The brake calipers boast a 10% increase in pad-to-rotor clearance to reduce noise while a separate bleed port and valve screw improve the bleeding process.
The new DN300 battery has multiple ports (3) on it's base, for a wireless cockpit set-up, only two SD300 wires (frame-size dictates lengths) are required and sold separately. Each shifter is otherwise powered by a CR1632 coin cell battery. For those looking for a Di2 Junction Box, the R9200-series moves the charging port, Function button and D-FLY communication system- plus the LED system indicator, to the body of the rear derailleur. The 4th generation E-Tube App simplifies the set-up and diagnostic process, with a much more effective interface.
