I have been chasing a phantom chain noise. I think it is the right front adjuster. I don't believe the teflon is worn to the rivets but it sounds like it. My tires were worn to different sizes so I blamed the noise on chain windup from significant different tire circumferences,so I put new tires on it,still have a noise though not as bad. I'm thinking of getting new chain adjusters complete from Recreatives. Anyone know what a complete adjuster is worth?
