I've got one of these Stronglight 49 (Marque?) with the outer ring mounted on the 50.4 BCD crank.



Every time this subject comes up I go through the posts, and I end up doing nothing.
I'd like to get smaller than my current 52/40. It appears that the TA or VO Grand Cru Outer can fit, but require the matching brand inner.
The tariff situation pretty much makes overseas ordering out of the question.
Does anyone have a simple solution, available from one vendor in the US?
Thanks
