yep a thin layer of branding by Merry Sales
Yokozuna started as Japanese brake housing but is now generic chinese catalog clones of Tektro products
TANGE tubing labels are actually a Maxway competitor in Taiwan that bought the defunct brand
Tanaka is their clones of Honjo, Wald, King Cage
IRD is kinda their Salsa in that it had been a company before, but now is their knockoffs of Paul and Sugino with no relation to the original better brake designs
Kasai Dynacoil is also theirs, buying from the machine shop vendor that fucked over Shutter Precision years ago to kick off that quality crisis and made SP start over
