My Ultegra 6600 shifters need replacing. My thought was to replace it with a new 5-piece 6800 set including shifters, front derailleur, rear derailleur SS, an 11-28T cassette and obviously a new chain.

Can I keep my current compact front crank set? I just replaced the bottom bracket. Will the 6600 brakes work with the 6800 shifters?

  • Why do you think they need replacing ? In my experience the shifter rarely need replacing unless you have forced it at some point. Most times problems with shifting are due to frayed or sticky cables.

The crank end generally is fine. Pre- and post-super SLR brakes and levers don't work together because they changed the cable pull. Presuming you have a 10-speed rear wheel, it can't take an 11-speed road cassette.
