Upgrading to di2 - TT Bike

[FreeSoul]

Hi All

 

Looking for some advice.

 

I am currently running a mechanical 10 speed SRAM Red Groupset on my TT bike with Aero QRings and a stages power meter (sram rival). I want to upgrade to di2 but not sure what components I can keep. I also run a set of 2012 Zipps which I am not sure will be 11 speed compatible but want to keep.

 

In order to upgrade to 11 speed di2, can I re-use my current QRings and crank and just upgrade RD, FD, shifters and Cassette and hopefully convert my current wheel set to 11 speed? Is this feasible or would it just be cheaper to buy an entire new groupo and convert my wheel set?

 

Any advice would be appreciated.

 

Thanks
