Pro gear uses a Rolon chain. Made in india.
Because of not so great reviews on that chain I have a pro-gear set on the shelf I replaced with Rollmaster that uses German Iwis.
Rolon makes two different grades of chain. What is referred to as the "gold" chain is just as good as the Iwis. The standard Rolon is the one with durability issues.
For what it's worth, I used Rollmasters on the last three engines I built, and keep two new ones on the shelf, but the ones on the shelf are quite dusty these days.
