I'd like to get a 50T chainring for my SRAM Rival crankset. I have the 39-53 and that 53 is a little ridiculous for commuting. I should've gotten the compact, but a 34 would mean swapping out my rear cluster and I didn't want to do that. Just figured I could get a 50T 130 BCD SRAM chainring.... BUT NO!!! I can't find one anywhere.
So my question is, which 50 tooth chainring should I look for that is ramped like my 53T SRAM and fully compatible (same BCD)? Can anyone shed some light? Will Shimano work fine? Are the ramps compatible?
