5 stars so far. Not that many miles on it. And it’s being tortured by a 1000 watt Bafang BBSHD motor. It shifts smooth and silent even under a load...I don’t plan on making a habit of it.
So I started with a ridged roller tensioner that only works pushing down. Never mind it was the cheapest 1/8 single speed chain...rather noisy. Less than ideal. So I found the Sturmey Archer tensioner on Amazon for $20 ! Have not even got it back together...because it’s been raining and I’m not running the beauty in the mud.
Maybe tomorrow when the street dries.;
