Answer of Antonino

It´s only for single chainring (1X). The tooth configuration (fine tooth - wide tooth) doesn´t allow it to be used with a double chainring.

Es solo para Monoplato (1X). El dentado que tiene (diente fino- diente ancho) no permite usarlo en doble plato

Answer of Antonino

I´m not sure if your chain length is correct now. If it is, you will need to increase it. You can find mathematical formulas online as practical methods for calculating the correct chain length (in your case, it could be 3 to 5 extra links). The practical method is best because the derailleur hanger needs to be in a specific position and under sufficient tension.

No sé si ahora tienes la longitud correcta de cadena. Si es así, sí tendrás que aumentar la longitud. En internet tienes formulas matemáticas como métodos prácticos para calcular la longitud correcta de cadena (en tu caso puede ser de 3 a 5 eslabones extra). Lo mejor el método practico por que la pata del cambio tiene que quedar en cierta posición y con suficiente tensión

Answer of Andrew

GRX outer chain rings have a BCD of 110 and the inner chain rings have a BCD of 80, so you cannot use an outer chain ring on the inner position.

It´s only for single chainrings. Its teeth don´t allow it to be used on double chainrings.

Es solo para Monoplato. El dentado que tiene no permite usarlo en doble plato

Answer of Christophe

Hello No, at least not with a grx crankset. 110 bolt spacing, so 80 outer and inner. If you find a mountain bike crankset with 110 inner chainring, you could mount it with a 48 max, so no point. Change the rear cassette instead.

Bonjour Non, en tout cas pas avec un pédalier grx. Entraxe des fixations 110 donc extérieur intérieur en 80. Si tu trouves un pédalier vtt avec 110 pour le plateau intérieur tu pourrais le monter avec un 48 maxi donc aucun intérêt. Change plutôt de cassette arrière.

Answer of Antonino

Valid only for single chainring (1x) so that the chain does not jump easily, it has fine tooth-wide tooth teeth that do not allow use with double chainring

Valido solo para monoplato (1x) para que no salte fácilmente la cadena tiene dentado diente fino- diente ancho que no permite usar con doble plato

Answer of Antonino

For 10/11/12-speed single chainrings. Depending on how the chainring teeth vary from the stock chainring, you´ll need to adjust the chain length.

Para Monoplato de 10/11/12 velocidades. Según varíes el número de dientes del plato respecto al originan, tendrás que ajustar la longitud de la cadena

Answer of Antonino

Yes, compatible with 4-arm crank and BCD 110.

Yes No problem. I changed the original 40 teeth to a 38. And no problems with my 11v 10-46 cassette. GRX 810 group but the 600 is the same.

Oui sans problème. J´ai changé le 40 dents d´origine par un 38. Et aucun soucis avec ma cassette 11v 10-46. Groupe GRX 810 mais le 600 c´est pareil.

Answer of David

Hi. This is a round chainring. It’s fitted to my GRX crank. I’ve had 2 Specialites rings - happy to recommend. But it’s not oval, Rotor has oval ones: https://www.tradeinn.com/bikeinn/es/rotor-plato-q-rings-4b-110-bcd-inner/139729225/p
