Is this 12-speed crankset compatible with a Shimano 105 11-speed drivetrain? Shimano's compatibility chart says, "no", but I know that they have been wrong in the past. I need to replace my crankset ASAP. It appears there are a lot of deals on this particular crankset and if it will work without chain rub on the derailler, I think I will get one. Funny....it costs less than the FC-RS510 right now. Thanks.

It should work. The 510 is the 11 speed version while the 520 is the 12 speed version. In reality, they are cross compatible.
