Hello, im searching for a lighter alternative to the Dura Ace chainringa in 52, 36 that would be awesome didnt find Something really lighter so far.
I don't think anything lighter really exists.
Cybrei do an alluminium set that is about 25g heavier. They also do a carbon/alluminium set that is about the same weight but probably shifts worse.
Carbon-Ti also do a set which is about the same weight give or take a few grams that'll set you back about 430 EURO.
The construction method of the Dura-Ace chainrings is incredibly light and stiff. It's pretty hard to beat by machining a chainring out of a lump of alluminium like most aftermarket manufacturers.
If you want to reduce the weight of that part of your bike you are going to need to change the crank arms and not the chainrings.
I've tried multiple lightweight alternatives including the Rotor rings. I wasnt happy with the performance of any and ultimately went back to Shimano chainrings. The weight savings weren't worth the downsides.
There absolutely are lighter alternatives even on aliexpress, just search "light chainring, but it may come at a significant cost to shifting performance
Can you share a link to one? I can't find any apart from the Cybrei which might save you 5g.
I found the zrace ones they are cheap and save more then 20 grams but searching Something lighter
How do the Zrace rings save 20g? Is there a different model I can't find?
Listed Zrace 52/36 weight - 148g
Listed Zrace 50/34 weight - 132g
Zrace Bolts + Cover - 29g
Durace 9200 50T - 107g
Durace 9200 34T - 32g
Durace Chainring Bolts - 6g
Maybe im wrong i thought i checked IT right, thanks for the answer

Fwiw I can't find any real lightweight rings on Aliexpress Zrace or others. Even the Cybrei comes up *only* if I specifically mention word Cybrei in search box other wise its just generic chain rings.
