più specificamente nel punto in cui dice:
Question:
What L-Rod size is recomended for this bracket?
Answer:
12.7mm or 1/2". It comes with sleaves for 10.5 and 9.5mm but I couldn't get them to work right. What also works is 3/8" hex rod and is what I use on my two main rack toms as I already had them and the drums slide off and on easier than with the 12.7mm rods like I have on my floor toms. These brackets work great, the only thing lacking is the so called memory locks, they give you height memory but not rotational which kind of sucks but I live with it. I even complained to Ludwig about it and they didn't seem to care.
Spero ti possa essere di aiuto.
Ciao
