Lockring Tool

[Distorted Vision]

I want to replace the Shimano Sm-RT70 Ice Tech Centrelock disc rotors on my Cannondale Synapse 105 Carbon road bike with Shimano Shimano SM-RT900 Dura Ace Ice Tech FREEZA.

The SM-RT70 uses this lockring:

which I think is the Shimano part no.: SM-RT81and the SM-RT900 uses part no.: Y8PV98010

I think they are same just a different colour.
Is Park Tool FR5.2 the correct lockring tool to use?

They're the same, only very slightly lighter. In weight, not just colour.

And yes, it's the same tool.

Was going to use the black one as this guy did as I agree they look better on the Dura-ace rotors:

Cassette lockring tool. Is same.

I noticed on YouTube they use the one with a guiding pin. Is this one better to use with thru axle wheels?

No need. The spline interface is pretty secure and the 40Nm torque is the same as for a cassette lock ring. Fasten dry (no grease).
