Hi,

I have a GT zaskar of 2000. I experience problems with a cassette cog 11-34.
When I shift to the 34, the dérailleur hits the cog. A new dérailleur doesn't help. Also changing the b-screw tension doesn't.
I'm wondering of for GT there are different sizes for the hanger, maybe it could help if I had a longer hanger, so the dérailleur hangs a bit further away from the casssette cog.

regards,

Johan
