Group SHIMANO GRX RX825 Di2 12V (Copy)

Designed for gravel bikers looking for adventure, fun and even competition , the Shimano GRX Di2 12-speed complete groupset offers precise, stable and reliable transmission in all conditions.

It features comfortable curved shifters in electronic version offering more control thanks to the anti-slip coating, a Shimano Shadow RD+ rear derailleur for better chain retention, and a front derailleur designed for precise gear changes. It comes with an RX820 double 31/48-tooth crankset and an 11/34-tooth cassette for optimum pedaling cadence. Its internal battery also simplifies charging and is protected from dirt, stones and external elements. What's more, the RX825 range uses a wider chain line, +2.5mm,
to offer greater clearance on wide tires.

Thanks to the Shimano E-Tube Project Cyclist application, cyclists can choose between different shifting intervals, customize shift button assignments or program different shifting modes
such as Synchronized and Semi-Synchronized modes.
