i think the power glide rings from the last couple of years are pretty stout. the first year Red chainrings were a little flex, and SRAM offered the 'SPR' rings to teams, as well as the 'Red front derailleur, steel cage'. the SPR rings became standard on the Red crank in '11 i think. if you get the rings w/ SPR on the back, they should work pretty well.
