campi rear cage is hitting cog help
i just put a new cassette on my road bike. i went from a 13 -26 to a 14-28 campi. I have a medium cage veloce 9 speed rear derailure on the front i have a 3 chain rings. I wanted more gear options when pulling a trailer. the problem i am having is when i am in on the smallest chain ring in the front and the 25 cog in the back the inside of the cage is rubbing against the 28 cog. I let out the tension screw as far as it will go to lower the derailure. I think its becasue of the jump from 25 to 28 all the other spacing is only 2 teeth apart. what can i do I cant use the 25 because of this.
I took it to the bike shop and they told me to file down the inner side of the cage. I dont know if i like that idea I still have the old cassette i was thinking maybe i could take out the 25 and put a 26 in there but then i think i might have the same problem with in 23 rubbing on 26. hepl me please
