I’m using a compact ultegra chainset with 11 speed cassette and I’m doing lots of endurance rides at the moment. The problem I have is that when doing group rides, my endurance wattage means I’m in a gear that’s either i. too high for the big ring, or too low for the small ring when on the flat. This means my chain is always at a horrible angle and is getting shedded. Is there a way that I can adjust the general resistance so that at a certain wattage, I can sit in a gear that keeps the chain nice and central?
