To the point that idk if it would be noticeable. I believe it is a superior alloy absolutely, but both are T6 and imho I think it’s more of a genius marketing ploy to get more $ for essentially the same product. Just my .02 cents. Anywhoo! Omniums are a great crankset regardless, and I would say that small amount of weight difference won’t be noticeable either. That’s just me though
I'd agree to an extent. The bike industry pushes stiffness a lot as a marketing strategy, and what gets lost in the fray is the fact that if A is stiff enough for the rider's needs, it doesn't matter if B is stiffer. Frames, wheels, and handlebars all flex more than cranks in most cases anyway. The Omnium crank is a great product -- easy to install, well designed and well made, durable, reliable. Only functional downsides are some inconsistencies in frame compatibility and some reported issues with the stock BB (though I've had no problems with mine). And it's pretty economical compared to the other performance oriented track cranks out there.
