Hi all,

I'm putting a new wheelset on my 2014 Tarmac SL4 Sport and thought I mights as well upgrade some of the cheaper Axis and Tiagra bits to an 11 speed Ultegra 6800 group.
Given the SL4 sport is a BB30 design can I just change the front/rear derailleur, cassette, brakes and shifters (plus cables, of course)?
Is there any issue with the FSA Gossamer working with the 6800 front derailleur, and do I need to upgrade the Gossamer to work with 11 speed?

Finally, do I need to upgrade the shifters immediately?
I have 105 shifters on there at the moment and would rather leave that until later if I can.
Cheers.

    Yeah the 10 speed chainset and fd will need changing if you want flawless shifting.

    Obviously you need to upgrade the shifters.

    In my opinion you should just get a wheel manufacting bb adaptor and upgrade the whole lot. Partial upgrade which youre planning wont look nice.

    Thanks for the reply- I actually bought the Wheel manufacturing BB adapter a few mins ago.
    I can get the full Ultegra 6800 groupset for £465 from CRC, so I guess it makes sense to do that.

    Cheers.
