Easy assembly and looks very good. It is compatible with the shimano r8000 and for the moment it is fine. Let's get sparks out of it.

I fall in love with 4iiii several years ago, and now I bought new Precision 3 which is lightweight and thin. 4iiii make great crank powermeters.

Compatibility of Precision 3 Ultegra R8100(left crank)

Byung Seok Moon - 30/06/2023

Can the Precision 3 Ultegra R8100 (left, 172.5mm) be mounted on the Ultegra R8000 (left, 172.5mm)? Or can I now purchase the Precision 3 Ultegra R8000 (left, 172.5mm)?

Answer of Amar

11 speed groupset & 12 speed groupset from Shimano are not compatible

Answer of Denis

Of course it fits. If the dimension is the same (172.5), then it also fits instead of shimano 105.

Hello, is it compatible with Garmin Edge 530? Thank you

Answer of Alessandro

HI. I paired it without problems to the Garmin 830. Both cycle computers connect in ANT+, so you shouldn´t have any problems. I am very happy with 4iiii. Alexander

Hi, What colour is the Ultegra 4iiii Precision 3 172.5mm crank please? Thanks Brett

The crank arm is identical except to the R8100 crank set. Basically it is an ultegra R8100 crank arm with the power meter fitted to it.
