If your Pinion H2R hub makes a creaking noise or has an interrupted engagement, the cause is most likely a poor lubrication or heavy contamination of the freewheel mechanism. Please check the condition of the freewheel mechanism. If necessary, clean the mechanism thoroughly and lubricate it sufficiently.
If the pawls show noticeable wear, please contact the customer support ([email protected]).
