Thank you slash and dweenk,
What I really want to check out is the max tooth count .
I found this chart which seems to say it is 42 T .
ADFC Fachausschuss Technik - Umwerfer
Also this koga spec that has it set up on on a 42 32 22 ;
Tourer
But in other links like the one Slash has shared its marked as 48T .
Confusing ,
J
