This is my first post, apologies if this is in the wrong section.
I have just purchased an elite suito, when pedaling the gears on the cassette are really grinding. I am using the 11-28 11speed cassette that it came with. My current bike and derailleur is set up for 11-34 on an 11 speed cassette, could this be the reason why its running so rough?
It’s not too bad on the smaller chaining, but whenever I move into the big ring its awfully loud.
