Description

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 11/36-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.

Manque d'accessoires

"Ce groupe est un cadeau. Je viens de le découvrir. Ce groupe est de très belle qualité avec une jolie finition. L'équivalent ultegra pour un gravel. Cependant ce qui est lamentable de la part de Shimano, c'est qu'il manque des petites pièces pour en faire le montage ( bagues pour tenir la batterie. . . . . etc) . Je pense que franchement ça ne coûterait pas bien cher de rajouter quelques lots de petites pièces pour éviter d'avoir à recommander des morceaux. Encore un brillant calcul d'un gestionnaire commercial de Shimano qui ne comprend pas que c'est franchement exaspérant. Perso je suis équipé en Campagnolo et ce n'est pas mieux. . . Pourtant quelle qualité cette marque !"
