@Donut!
Hello all, I don't usually post coz I'm pretty savvy on the mechanics thing but this is puzzling me!
Whilst turning the pedals, my chain goes from being super tight and grinding, to loose enought to flip off, then tight again!
Obviously something is out of line, but what?
I recently changed my chainring and have tried it in 3 different positions so far, making sure that it is centered correctly (and yes its the correct BCD) and it's not solved it. My chain was never noisy before, now it's terrible.
I tried flipping the BB over incase something was bent there, but no change.
Help please!
Cheers
D!
