Shimano announced this week the launch of the new line of Dura-Ace components R9100, the most sophisticated group of Japanese brand. The big highlight was the new crankset with integrated power meter, the first in its history.
The company presented further new pedals and wheels, more aerodynamic and lightweight. For electronic Di2 line (R9150), the highlight is the exchange of synchronized gears.
The new power meter is the FC-R9100P, that Shimano claims to be the most accurate and sophisticated available for your cranks. It provides data on the right leg and the left, and pace data. The sensor is located in the inner part of the integrated crown, while the receiver within the spider, as in Pioneer meters.
A very interesting feature of the integrated meter is that athletes can exchange the crowns without affecting it, which usually generate major disruptions in other brands. It has rechargeable battery and can be updated and checked applications on smartphones, as it has, in addition to the ANT + data exchange protocol, connectivity via Bluetooth. To be integrated, the device can not be purchased separately.
Another interesting point of the new Di2 group is a wireless transmitter that will connect the exchangers to a smartphone (probably Android and iOS), for adjustments and calibrations, as well as updates. A novelty, inherited from the electronic group mountain bike XTR is the exchange of synchronized gears, which aims to prevent the crossing of the current, so the exchange rate automatically adjusts the front crown. The new wireless transmitter has the ability to transmit data to compatible group cyclo-computers, including information on battery life. For those who already have Di2 groups with E-Tube, you can perform the upgrade to the new system.
The new rear exchange come to accept the new cassette 30 teeth, compared to 28 teeth of the previous line (9000 series). There is also the possibility of integrated hydraulic brakes for both wheels as C40 to C60, both available clincher or tubular.
Shimano to begin offering news to market until September 2016, all still no set price.
