Hello,
On my Fiido T2 a „tensioning roller“ or a shift roller is used as a tensioner / derailleur. However, this roller has no bearing, but only a sleeve pressed with the guide. The construct makes a quiet but clearly audible noise, so I’m looking for a replacement for it.
So we are looking for a roll with 12 teeth, about 50mm diameter with (ball) bearing with 8mm hole.
With everything I find, it fails because of the 8mm hole. But it is needed for the holder there, because it is screwed with an 8mm bolt.
