I learned Wipperman Connex won't run on narrow wide chainwheels, like Lekkie, race face and eclipse. Truly a quality chain. Very disappointed. Since 132l are a pain to find and buying two and making a chain gets pricey, I've taken to buying cheap Sunlite, and keeping a spare and smallest chaintool I could find in my battery bag. Got a good deal on 5. I bought a chain measuring tool and staying on top I've not been burned on a ride. BUT I'm a casual rider, I still would have liked a quality chain. There are other chainwheels but offset issues with DIY mid drives.
