Just recently installed a Tannus Armour in my rear tire and when I put the tire back on I’ve got no tension on my chain. Here’s what I did:
– put the bike into it’s hardest gear
– turned off the clutch
– removed the wheel
– installed the insert
– put the wheel back on
– turned the clutch on
The bike seems to shift alright and when I’m in my easiest gear the tension seems good. It’s just when I’m in my hardest it’s so slack it’s laying on the chainatay. It wasn’t like this before I took the wheel off and put it back on. Rear wheels are always kind of tricky for me so wondering if I screwed something up taking it off/putting it back on. Maybe I’m just stupid and totally missing something. Any help as to what this might be would be greatly appreciated!
No chain tension all of a sudden?

It looks as though you loosened your sliding drop outs and they are all the way forward now. You need to return the drop outs to the original position.
Your derailleur is all the way back, so the spring is fine. Double check your chain routing to make sure you reinstalled the wheel right. You mentioned that you prefer the wheel all the way forward so if all else is well then your chain is simply too long.
Derailleur is almost horizontal. Did it get loose and/or rotated forward?
I’m pretty sure when you tightened your thru axle the derailleur hanger turned slightly
Did your B-screw slip past the nub on the derailleur hanger when you wrestled the wheel back in place?
Your clutch may need servicing. Check out this [video](https://youtu.be/X_aQxSQahrA?si=VE3P22eWYGT50kYQ)
That’s not good
