FSA Energy Adventure Modular Crankset Puzzle

[Moneywatch]

Hi, all. I bought a FSA Energy Adventure Modular Double Direct Mount Crankset. The crankset came with a 50/34. Installed the FSA bottom bracket on my Serotta Fierte IT project. Everything went fine until I noticed that the chainrings were not aligned. There was a 1/2 inch "wave" on the chainring as I slowly turn the crank.
Emailed FSA and was promptly sent a replacement set of chainrings in 48/32. Changed the chainrings and the same 1/2 inch "wave" is still present.

Anyone had a similar experience with this crankset? Everything fits/sits right with no gaps or play. I am stumped.

Sounds like FSA.

Can we see some pictures?

Here are a few photos. I will send the unit back so they inspect it and send me a replacement if need be.

are you sure its the chainrings that are wavy and the problem is not the crank or the BB?

take the chain rings off and put them on a flat surface. make sure when reinstall they sit flat on the crank . just a tip.

I am happy to report that I sent the crankset back to FSA. And upon their inspection, the crank was part of a small batch that had production issues. The sent me a new replacement crankset under warranty. They were very responsive to my questions and claim. A shoutout to them for the great service.

I was quite incredulous to once receive a new 105 Octalink crankset with this same sort of wild misalignment of the right crankarm. Careful inspection showed that the recepticle had simply been formed/broached/machined off-axis with the rest of the crankarm, yet with all of the splines still in perfect condition and no detritus hiding in there.
