I have found that the SRAM chainrings shift as good as the DA7900 that they replaced. This is on a S975, standard, GXP using a DA7900 drivetrain. When I was dialing it all in, I noticed that if the indexing was a few turns off, they made an awful grinding sound. The Shimano didn't do that.

my sample size was small, so i'm fully aware of that. sometimes if one has an initial poor experience with a product (that could be luck of the draw) they won't return. while i like to THINK i put out tons of power, that's more in my head. it happens that sram rings are the only ones i've bent.

granted, these were 110bcd/50T rings.

do you have the SPR or non-SPR 53/39 rings?

the DA rings (in my experience) just seem to work better than anything else i've tried, particularly with di2 FDs.

look for the code "SPR" on the rings themselves -- i don't have any red rings in my possession right now, but as i recall it was imprinted on the inside of the big ring. the SPR version -- as i understand it -- was a stiffer version of the ring ("SPRinter"?). i believe it was created in response to some issues with earlier batches of red rings. my experience bore out that the non-SPR versions i used (at the time were prone to bending teeth/breaking.

i'm sure someone will correct me on some detail.

ah, here's a photo & bit on it:

i think sram shaved grams by machining the non-SPR rings a bit more.

Well my Quarq is a plain vanilla S975 GXP with the "new" Red Black rings. I'll check. I doubt it, though.

Hat's off to you, tetonrider. Learn something new every day. My inner ring is stamped SPR.

mine says spr too.  I'd have preferred the lighter one.

glad i could help. i think you'll prefer the SPR version -- in my limited experience it should hold up a bit better.

mine says spr too.  I'd have preferred the lighter one.

you could always swap rings. in fact, there are probably more folks who would be interested in the SPR rings -- maybe you could do a straight-up trade (even if yours are lightly used).

or course, i'm a guy running shimano rings on sram crank arms, so what do i know? :)

Also because there is no actual difference between the compact and standard versions except the bolts of the spider, I had it changed out to a compact at that time, and was only out the cost of 110 the BCD chainrings.


umd: we corresponded, i believe, on this a long while ago. i've been using R700 rings on my compact because i wanted to stick with shimano rings (sram force (110) rings did NOT work for me), and DA7950 (110) does not work with quarq cinqos.

at one time, specialized rings were not working well with quarqs, though i believe that has been resolved with newer specialized rings (and perhaps the change in the specialized cinqo).

what compact rings did you find worked best?

i'm a little leery of trying the sram red (110) rings given my experience with force. i suspect the red outer is stronger than the force 50T, but the inner rings are identical, i believe.

i initially chose the R700 50/34 as it was ultegra level and had more of the design (well, at least the "look") of the DA7800 53/39, and i had good success with the DA7800.



i'd really love to go with DA but just can't. ulty 6750 is not an option either.

should i look for 6600 rings?

the 6650 looks lighter, for sure -- but i am mainly interested in stiffness and shifting quality.


any other good options?

The compact is on my wife's bike. I think it just uses the standard rings that would have come with the 950 (iirc). She doesn't really ride it enough to give any feedback regarding the quality or performance of the rings, sorry.

I've been happy with my Stronglight standard rings, but they are worn and I need new ones and they are a little hard to find now.

Try the UK dealers. They usually have Stronglight.

I've heard mixed things about pretty much everything. Funny thing about people... they have opinions, don't usually agree  :thumbsup:
