Excelente opción

Compré esta rueda libre de 8 pasos para armar un rin para rodillo de entrenamiento. Considero que es una excelente opción si no se quiere gastar mucho dinero. El material es resistente y ha funcionado sin problemas.

Great cheaper alternative!

Definitely smooth and quality at least for a cheaper alternative anyway! When i opened the package first thing i noticed was it was pre oiled!? I have not seen one pre piled til now. Very grateful on that for sure!!! First thing i did was stick my fi n gers in it and reverse spin to see if any catches and how smooth it would spin, to my great and grateful satisfaction it was smooth with no catches. Nice audible clicks from the teeth inside the set so for me functionalityis great! The material seems really durable no bends or chips in it! I might actually get my bike back up and going sooner than i expected excited for that! If you have a bad freewheel try this one out i dont think you will be disappointed. I think it will give me plenty of power.
