WTD: Shimano compact crankset 175mm - modern (hollowtech II)

[fids]

Hi

Not really that retro...
I'm looking for a compact crankset / chainset in 175mm.

Ideally Ultegra 6600/6650, but would consider 105/Dura
50/34Teeth...
I currently have 6600 cranks with matching hollowtech II BB, so would need to work with this

Thanks
Fids
