Are there any other chainrings to consider? I see the shifting performance on the blackspire rings seem to vary from great to terrible. I'm planning on switching my Noir cranks to a 2x9 24/36 combo, so I will want the rings to be ramped.

Race Face does a 24/36 combo... you'll want to check to see if the clocking/spacing is right for your cranks (it doesn't work with Shimano cranks last I checked, though they are developing some different options for compatibility with other mfr's cranks).

I have not had problems with the Pro rings (not to be confused with Super Pro). The website says they work for 7/8 speed, but I run 9 speed with no problems.

I've been using the Super Pro chainrings for 2 years now. Zero issues with shifting. I am running a 3 chainring setup now, but will probably switch out to a 2 chainring set before spring. Maybe a 38/26 setup.

I am running both a 22/36 and 24/36 Superpro set up on 29ers with Sram Force/Rival FD's. They shift spot on for me and I tend to shift up front quite bit because my knees do not like me grinding out climbs in bigger gears.

Thanks for the replies. The raceface combo looks nice, but I ended just going with the blackspire super pros.

G-live, is your Sram force a top pull high clamp?

I've used Super Pro's for the past 2 years - been perfect for me. Very good quality rings - big fan of Mono Veloce rings as well.

Has anyone tried to use the Shimano SLX M665/7 fd which is made for a compact double or have a recommendation for a fd that has a shorter cage so it can sit lower on the top ring? I plan on trying my X9 top pull FD but it appears that it will sit high on the 36t ring.
