Product Customer Reviews

Good product. High quality
B'twin derailleur is good enough for everyday cycling.
It would be better if the cage was medium length instead of small so you can run larger cassette ratio or larger front chainring. Otherwise it performs well despite limitations of use
I buy lots from here good value for money
Bought as a replacement for a failing part - simple to install on the bike and set up - it probably still needs some tweaking as the new cables stretch!
Rápido, conciso y perfecto
Quise solucionar este problema para que la bicicleta estuviera perfecta. Pero el repuesto al no ser exactamente igual al original, en una combinación de los cambios se quedaba la cadena atrancada, por lo que perfecta no se quedó. Aunque me trataron muy amablemente, yo contento no quedé.
Atención magnífica, producto cumple perfectamente las expectativas. Buena calidad precio.
Muy bien
Es un artículo normal, que cumple perfectamente su función.
Muy buena relación calidad- precio. Montar ajustar y listo.
Fácil de montar y buen producto
La instalación es sencilla,pero yo particularmente tengo un problema y es que me toca la roldana superior en el piñón grande cuando lo uso con el plato pequeño y no cambian los piñones,tendría que tener algún tornillo para poder regular la altura de las roldanas cómo hay en otros modelos
BUEN ARTICULO CALIDAD-PRECIO, NECESITABA RENOVAR EL CAMBIO DE UNA BICICLETA DE 24 PULGADAS DE RUEDA, Y ESTE ARTICULO ME HA VENIDO MUY BIEN, FACIL Y COMODO MONTAJE, Y ESTUPENDO FUNCIONAMIENTO.
EXCELLENT
