# BB30 Crankset Upgrade

Hey all,

Im potentially looking at getting a new crankset soon for a CAADX 105 2020 which has a bb30 bottom bracket.

At the moment i have a FSA Omega 46/36 but im looking for something in the range of a 50/34 or a 48/32. I have looked at some FSA cranksets and im struggling to find ones for bb30 bottom bracket, most are now using bb386. What would be my options for upgrading?

Also if i went from a 46/36 to a 50/34 would i have to reposition the front derailleur as im assuming it will be a large sprocket?

Thanks for any advice.

76ballysmate: compact cranksets like that use a smaller BCD diameter to accomodate for smaller chainrings so normal road chain rings don't typically match the BCD bolt setup of the compact crank.
