Your 8 speed Claris brifter will not work with a 10 or 11 speed system. You will need at least 1 new brifter to shift the new rear der,, new RD, new chain, new cassette, maybe a new RD cable and housing. new bar tape. $200 or so if you shop around. Microshift components are a little cheaper than name-brand

You may be able to keep your FD and the associated brifter if 10/11 speed chain will fit the existing chain rings. You might also be able to do this upgrade using your existing wheels.
