Super Record crankset, front and rear derailleur and a new Sram chain. On the big ring its smooth and quiet, but on the small ring it sounds like the chain is rubbing on something when I put pressure pedaling. Its smooth in the stand but sounds like crap when I'm riding it. I can't see anywhere that it would be rubbing. I have no idea where to go from here. I pulled the cranks and bottom bracket, checked everything and reinstalled them. I even thought the spider on the cranks might be cracked but I can't find any damage.
