• I converted my ebike to single speed, and I used all 1/8 drivetrain parts. I had to get a chain tensioner and it's my first time actually using one. I got the XLC CR-A03.

    However, it seems the track chain I'm using is a bit too wide for this tensioner and under stress will rub against the little cage shown in the picture - and the master link, which sticks out about 1mm, rubs against it every single rotation no matter what.

    I've not seen anyone mention this online and it seems brands don't even specify if their tensioners are supposed to work with 1/8 or 3/32 chains, which I find strange and leads me to believe it's me who's done something wrong here. Or is this expected?

    I really don't want to spend money on a 3/32 cog, chain and chainring now...

  • I have exactly the same thing. I crushed/bent the cage to give it more width and it has lasted many muddy winters
