Fairly novice cyclist (adventure races only) here.

I have a 2009 Giant TCR Advanced 1 running 10 speed shimano 105 and was wondering is there an issue upgrading the groupset to the new 11 speed 105 5800? Googled it and can't find any relevant info, and I honestly don't understand the sizing and ratios stuff. I intend upgrading all or part of the groupset and adding a shimano dura ace C35 wheelset. All advice welcome.

Cheers.
