I like the pedals and the chainrings very much . It is a good concept, rolling smooth , more power and less fatigue. I am very satisfied.
By the other side, I think there is my duty to give you a complete feedback, with good and bad.
About the bad things, there are some weaknesses as follows:
1.The pin screawed on front on pedal is weak, and get damage on 700-900km of ride.I solved this problem assembling the pin with a screw M5 and a nut .I think there must redesign this pin, even not have a desmountable pin.
2.Because the bearings are solicited in defavorable position , there can catch a play, that can be in some discomfortable riding.
There are some improvement that the producer must take.
Anyway, I will buy same pedals, even there are some weaknesses.
