The issues with the Pinion tensioner are that it isn’t ISCG compatible and the huge spring it runs (not visible in photo) is the constriction point with the tire.
I’m running a smaller tire (2.35 E13 SS) which lets me tuck the tensioner up more than in this photo. I’ll also be drilling new holes in the back plate I have it mounted to to change the position a little - it’s a work in progress.
That said - zero dropped chains, the system is very low drag (very efficient) and it moves with impacts so I feel it will prove to be more resilient.
I’ve used all manner of tensioners over the years from the Paul Melvin to the Alfine.
Most recently I was using an old non-clutch XTR derailleur. A clutch isn’t needed for retention in this application.
Cheers!
