Has anyone used this can provide some feedback? I am thinking of getting one to replace the force big ring, setup for fast and flat rides. Is it worth the weight penalty, is it alot stiffer and would shift better?

Stiff? I've never ridden a ring that wasn't stiff. They do shift well but I really don't have that much time on them. If you create that many watts that your standard rings are an issue I'm sure they have to be much stiffer that Force rings and I'm pretty sure Red rings are stiffer than Force too.

I use them on my TT bike. They work just fine. You are not going to be any faster/slower compared to your standard chain ring if using the same size ring (like a 53 on both). Where you can pick up some benefits is by going from a 53 to a 54 or 55t ring. It really depends on the course that you are racing on. At the same rpm, a larger ring will add speed and/or provide a better chainline efficiency (a straighter chainline) becuase you won't have to shift down on the rear cassette asw much.

I run one on my Sram crankset - no dramas and plenty stiff.
