Replacing a Force Chainring with a Red Is it possible to replace a compact 50T chainring from my Sram Force set-up with a 50T Red chainring, they both have the same 110 PCD so I don't see a problem, does anyone know if I'm wrong?

Thanks
It is possible, as long as you use the SRAM Red Black Edition 2011 or earlier.

The new 2012 Exogram SRAM Red requires a different front derailleur design, and while it will physically bolt up, it won't shift well at all.

Any other SRAM compact (110 BCD) chain ring will work fine.
