I am considering trying the 42 tooth and 36 tooth Lekkie chainrings but don't know if they are offset. Does anyone know? I am currently running a stock Bafang 46 tooth on my BBS02 which has approximately half inch offset. It appears my bike frame can accommodate up to about 3/4 in offset. My preference would be to run an offset as opposed to no offset. This would help my chain alignment.
