Hey guys,

It’s my first time on this forum and I am here with a question about my 4iiii precision 3+ pro powermeter with a Shimano r8100 ultegra 12 speed crank.  
I am U23 rider and a 52t isn’t big enough for the races. I am looking for a bigger chainring (54t-55t) for my bike that fits with the drive-side powermeter. I saw that Rotor has some chainrings that are compatible with the Shimano cranks but I want to be sure it also fits with the powermeter. I know that the dura-ace 54t is an option but as a student it is an expensive option for a bigger chainring. My question for you guys is that maybe someone has tried to mount a bigger chainring that fits on the crank with the powermeter (the brand of the chainring isn’t important). English isn’t my first language so I hope you guys could fully understand. 😀  
Thanks for the help!

Kind regards,  
Jelle

I’m from Belgium, I contacted the 4iiii online service and am waiting for a response. I was just hoping that there may be some people here who have had the same problem and found a solution.

Sell the drive side power meter as it doesnt work. May as well just use the left side.  
Then use the money to get the dura ace chain ring. They are fantastic at shifting.
