Fitted a chain tensioner today (first time I've used one) ... went out for about an hour on the trails (in the heaviest rain I've seen for ages - brilliant fun 😀 ) and ended up taking the roller off as, every climb I did, the chain kept sucking up, sometimes jamming.
Is this normal with chain devices?
Nb: it's a 3 ring set-up.
Is it designed to work with 3 chainrings?
I've not heard of one that is, i could be wrong though.
It's an e-thirteen Heim model specifically for 3 chainrings.
Is there a particular gear ratio it seems to happen in, or maybe more on one chainring than others?
You mentioned it happens when you climb, so i'm guessing smaller chainrings/ bigger cogs on the cassette? Most of my problems like this have come from the chainline being a bit out, might be worth exploring?
