These are the Made in Japan isolation spike/disc set. Unlike the aluminum and titanium versions from Nordost (that we have for sale separately), these Japanese alternatives are made from 99.98% magnesium. They are lighter than the aluminum and titanium sets from Nordost but seems to work just as well. Being that they are magnesium, they have a gun metal pewter finish instead of the “shiny” aluminum and titanium finish. Maximum load for the set of three you see here is 60lbs.
Cosmetically, the set looks good. Minor scuff marks here and there common with use but nothing major. We have the original retail boxes that they are sold in.
