Shimano SPD-SL pedal tension adjustment not clicking, possible counterfeit?
The &quot;click&quot; you are referring to is inherent to the design of Shimano's SPD, SPD-R and SPD-SL pedals. Each click signifies an increase in torque of the spring which tightens the retaining jaw.
Broadly speaking, there are two general possibilities. The first is that the tightening mechanism has worn out and the clicks are now overlapping with one another. The pedal in question however, is assumed to be genuine, but worn out.
The second is that you have acquired/purchased a counterfeit and hence, the poor attention to quality resulting in the lack of &quot;steps&quot; or clicks in the tightening mechanism.
