Just installed this pretty old Truvativ chain guide, and the chain has a kind of bumpy/chattering noise and feeling/friction when pedaling that increases when pedaling hard. Is this normal? I feel like my chain will just eat through the plastic rollers. Sorry for the probably stupid question as I have never used a chain guide with rollers like this before
