fyi, (shop owners view) Madison have seen a massive increase in fake shimano, the common outlets it is coming through are Amazon, ebay and Wish, i have seen some in the shop where customers have bought it online and asked me to fit it. the shimano EZ fire sti units look very close to being right, also 8speed rapid fire shifters, both seize up pretty quickly. also cheap road cleats, the SPD SL, mainly in the yellow option get faked, they break easily and wear quickly.
the fake stuff used to be badged as "shimang" the font was the same and the G looked close to a shimano letter O hence the confusion when customers bought it but now they are just copying the name completely.
