st60 rotor wear

[Dreamer99]

Here is a picture of my current rotor condition. From what I have read here once the cracks reach the edge of the rotor it’s time to replace them. I have a two day track event coming up. Do you think these rotors have enough life in them to get through two more days?

Try and measure the thickness of them

[Dreamer99]

They are a consistent 34mm all around

Do your finger nails catch any of the cracks? They look like mostly surface cracks to me

[Dreamer99]

I can feel them but can’t jam a nail into the crack

That's a coin toss.

Also why I keep a spare set of rotors.

This is a good rule of thumb how to inspect rotors for replacement.
