Advice please. My chain slips badly when pressure is applied when I'm on the large outer ring. I have a Shimano compact drivetrain. On the large ring it will not go into the lower gears without the chain slipping to the small ring or even slipping off the inside of both rings.
Can someone advise what I need to adjust to ensure the chain stays on the outer ring when shifting between high and low gears. Note there are no issues when moving the gears up and down on the small ring.
Many thanks in advance.
