Just trying to get a feel for when people replace their brake discs.
The wear limit on mine is 4mm.
The original was about 4.5mm.
With a micrometer I measure 4.13mm.
Is this cutting it a bit fine for a race bike? Or nah, go hard till they look likt paper?
What do people think is a good time to replace them?
50% worn? (4.25mm) 80%? (4.10mm)
