Welcome Donny!
Can you please repeat your text without the (poor) translation tool?
Some of us are capable of at least reading English, so a translation should be no problem.
As far as I understood:
You want to purchase a new chain as you are replacing the rubber tubes anyway,
and you are looking for recommendations for O-ring chains like e.g REGINA chains (520 size/102 chain links).
And as O-ring chains are supposed to have slightly different measures you are wondering if this could lead to more friction in the tubes and more heat therefore.
Did I get that right? I guess so.
Let´s hear what the old and experienced ones say...
So, Leute, hat irgendjemand Erfahrungen mit O-Ringketten für die Silver Star?
Gibt es Empfehlungen?
Gibt es bei Verwendung von O-Ringektten Probleme mit den Kettenschläuchen?
Gruß
