So when I read the manual, it says the 105 pedal I have (5800) will have a click when tightening or loosening the tension adjuster, supposedly 4 clicks for 360 degree rotation, however mine don't click and just twist.
Now, I had someone I know just got scammed buying a fake Ultegra pedal and that got me into researching if the 105 has fakes, which... surprisingly does.
He said (I have not confirmed if this is true) that one of the signs of fakes are the tension adjuster not clicking when you turn it. I've had a R540 pedal in the past that clicks, but later bought another that doesn't click, and so I never had any suspicion when buying a 105 which also don't click. I thought maybe they changed it in later releases?
So if you have a 105 5800 can you confirm that it clicks or not? or do you have any Shimano pedal that you know is genuine but doesn't click when turning the tension adjuster? that would be great, thank you.
Edit: Additional info, mine weigh 135.3 for each pedal, which is 270.6 for both.
Edit 2: So I asked a friend who had the same pedal and his have clicks, so the answer is very likely that mine is fake. Unless someone else chime in who had the genuine had one with no click like mine.
