So I'm considering boosting some speed by swapping out my default chainrings on my BBS02 and BBSHD.... 52T and 48T respectively, via Lekkie and Luna.

My question is, do I need to replace the chain with the size increase from the default bafang 46T, and the additional chain inner adjustment?

Thanks.

My 42T Lekkie Bling Ring says 7,8,9,10,11 speed right on it, so a chain for any of those should be good to go. I think even a 1/8" will work on them.

Remember the Lekkie is a Narrow-Wide design, so you have to put the thick teeth in the large chain openings when you install it. The Narrow-Wide design helps keep the chain on and less chain drops.

hmmm oops, I wasn't paying attention to that when I installed my Bling Ring last week, or my new chain on Monday evening. I need to check to see if I just happened to get it right. 50/50 I guess, seems to ride okay still.

Yeah, it's kind of hard to put it on the wrong way. The chain won't go into the sprocket cups properly. It's very noticeable if you are paying attention. Even an 1/8" chain won't allow the fat Lekkie teeth into its' small slots, so 3/32" just ain't going on wrong without you noticing it (hopefully).
