GRX Di2 goes semi-wireless <\/p>
Shimano has announced the release of GRX Di2 RX825 \u2013 its long-awaited 12-speed electronic gravel bike groupset.<\/p>
GRX Di2 RX825 adopts the same semi-wireless design first introduced on Shimano\u2019s road-specific Di2 groupsets, with a set of wireless shifters paired to semi-wireless front and rear derailleurs.<\/p>
The derailleurs are then wired to, and powered by, Shimano\u2019s standard separate Di2 battery.<\/p>
The rest of the GRX Di2 RX825 groupset is made up of existing 12-speed components from Shimano\u2019s GRX RX820<\/a> mechanical groupset and its range of electronic road groupsets<\/a>.<\/p> Unlike the original GRX Di2 RX815 groupset<\/a>, GRX Di2 RX825 will only be offered in 2x (\u2018Undroppable\u2019, as Shimano refers to it) configurations at launch.<\/p> Shimano has confirmed 1x GRX Di2 RX825 \u201cis coming\u201d, but it declined to offer a specific timeline for this.<\/p> Shimano has also announced a new shifting mode called Front Shift Next, for GRX Di2 RX825 and its 12-speed Di2 road groupsets. This enbles users to designate any Di2 shifter button to actuate a front shift (in either direction) when pressed.<\/p> A limited-edition GRX pedal set is also available, which takes a Deore XT SPD pedal<\/a> set and adds \u2018\u200b\u200bUnited in Gravel\u2019 graphics.<\/p> Simon von Bromley has weighed every component of new GRX Di2 RX825 and you can read up on his findings here<\/a>.<\/p>
