Ultegra Di2 10 to 11 speed mixed components help

philwint

hi,

My old ultegra 10spd front mech broke (snapped cage). So I took the opportunity to try to switch to 11 speed partly because 'why not', and partly because I couldn't find any old 10spd mechs to buy.

So after researching on the web it seemed that I needed to replace both front and rear mech with the 6870 versions

This I have done, just a simple unit switch of both mechs

All went very smoothly with the major snag that nothing is working!

If i hold either shifter in for a few secs the battery ok green light comes on. but holding down the button on the junction box that usually allows micro adjustment of the rear mech, or to remover the crash protection does absolutely nothing.

So can anyone offer any help?

Do I need to swap something else out? do I need to plug into the software (at my LBS)? Or anything else.

Thanks in advance

You will need to get the software updated to allow 11 speed operation . Just need to plug in to the software via a sm-pce1 unit . It's a quick enough job if you can get to somewhere with the interface, you can set shifting speed, enable multishift etc as well.

I might just brace myself and by one - only £119 on CR

Then I can fiddle to my hearts content

They're well worth it. Owning one allows regular updates and checks that everything is hunky-dory, and the opportunity to play with the settings, including changing what each switch does.

So I bought the interface ans now everything is working fine with the latest firmware as suggested

Thanks

On fiddling: All I have tweaked so far is to make the rear shifter step through the whole block while the button is pressed. I've been away for a few days, so haven't had a play outside yet, but seems to work very well on a quick 5min test on the turbo.
