Looking for a new chainring, does brand matter that much?

Looking for a new chainring, does brand matter that much?

So I have a Ritchey WCS Octalink crankset that came with a 38/48 set of chainrings (130mm BCD) I am looking to bring this to a 38/52. Now I have a shimano 105 52 chainring sitting around but the problem is that:

A) The chainguard tab will not align with the crank arm since it is simply situated in a different part of the chainring (not really a big problem)

B) The instructions for the 52 chainring say they should be installed in the proper rotation for best shifting.

I know that neither is a HUGE problem and I can live with that.

My big question is if there is another chainring produced that is designed to work with Ritchey cranksets?

Bikes: too many bikes from 1967 10s (5x2)Frejus to a Sumitomo Ti/Chorus aluminum 10s (10x2), plus one non-susp mtn bike I use as my commuter

As you apparently know chainrings are not quite universal. If you stay within brand, and check specs carefully you'll get best fit, maximum performance, and benefits like phasing for crisper shifting.

That said, the difference isn't earthshaking. Obviously you can't do anything about the anti-jam pin, but that isn't a crisis. As for the phasing, odds are you'll never get it perfect, but we managed to shift double and triple chainrings for decades without shift ramps, pins, shift gates and phasing. You can also rotate the inner and outer rings trial and error looking for the best phasing and get it pretty well dialed in. So it may not be perfect but after riding it a while you probably won't notice the difference.

BTW- I may tend to down play this issue, I still ride my old SunTour Superbe Pro cranks, and prize the ability to use any size chainrings I choose like 45/51 to optimize the gearing.

I had an old 110/74 Suguino crank with 52/42/26 "flat" chainrings on my rain bike for a couple of years and the shifting was adequate, particularly if I was careful to shift before the chain tension got too high. I was using dt friction shifters mounted on Kelly Take-off brackets

Then an 8-speed era Shimano 105 triple crankset was freed up when I upgraded the bike it was on so I replaced the Suguino with the Shimano. The improvement in shifting ease and accuracy was VERY apparent, particularly under load, even though I continued to use the same friction shifters.

I have had good luck with 52t FSA rings--but mine are 110mm bcd. I would think that 130 bcd 52t rings would work well also. Mine are ramped and pinned for easier shifting, too.

Out rings are ramped and pinned. Therefore unless OP got some real old 52t, you should be fine with shifting upward. If you're double, there's no worry about ramps and pins since it's just a drop down from the 52t. Inner most rings don't have ramps and pins.

yea its is a very very new chainring and it is ramped and pinned. I was more wondering if there was a particular brand like FSA that would work with a Ritchey crankset? Since I can't seem to find individual Ritchey chainrings.
