Issue:
Front chainring lifts the chain up, and this also causes rear to lift up.

I just replaced my chain with the exact length calculation for my new 11-30T cassette and 54T front chainring. I put this on my trainer. Needed a new chain since my original cassette on wheeling 11-34T and didn’t want to chain break that chain or mess with that configuration.

So what’s exactly wrong? Is it the B tension or something? It’s not going side to side, I checked the front alignment just up.

Thank you!

  1. Like somebody else has commented – your quick link isn’t properly engaged. Rotate the pedals until the quick link is above the chainstay, hold the rear brake lever and push down on the pedal to fully engage it.
