    Good Morning,

    Heading to the alps soon and need to have some more bailout gears!!!

    Already have a 32 cassetter with long deraileur /chain installed but looking to increase it to 34 if possible.. Option does not appear to be available with  the Di2 6870 Groupset and wondering if I could use Shimano Ultegra HG800 11 Speed Cassette 11-34?

    Many thanks for reading and hope you can advise..Hip is not 100% so need to be able to spin up those mountains!!
    Cheers, Ed

    It works fine on my 8000

    It works fine on my 8000 series with long cage. Make sure you fit the 10-11sp spacer though as is 10 speed width at the splines. You shouldn’t need to re-index the derailleur then!
