Hi im a newbie on here and wonder any one has used these type of chainrings https://a.aliexpress.com/_mPG8SCc they are the zrace ..fonvo or
Advanced brand but look the same it's to suit shimano 105 fc r7000 if I can get a year out of them ill be happy and they shift ok or should just buy new crankset such as senicx pr3 not after carbon cranks tia ..
I recently bought a Fovno 110/5BCD 50/34t chainring set, and the shifting is as good as Shimano. I only have less than 1000km on them, so I don't know about durability yet, but the teeth look to be in great shape so far.
I would not replace a R7000 crankset with Senicx crankset. A Senicx crankset
with spider will be heavier than the Shimano R7000 crankset.
