Question about brake rotors/wheels

[ygolohcysp]

Okay, I'm coming to terms with my situation of not being able to afford a track bike right now, and am thinking along the lines of having two sets of wheels. One with sport tires for things like track days and rallys, and one with touring tires for things like commuting to work and touring trips.

This brings up a question of which is better for the brakes/wheels. I know that not all rotors are equal, even if they look flat and smooth. If I have two sets of rotors mounted on respective wheels and swap between them, it seems like it would wear the pads faster, and possibly require a little bit of seating time before using the brakes hard, like on the track. I may be off base on that. But with using the same rotors and swapping them back and forth, it seems like there is potential for wearing the threads in the aluminum wheel.

So, which is best?

Cheers,

Our pads work by depositing a small layer on the rotor, and the remainder of the pad "grabs" onto that. This layer protects the rotor from wear most times unless somthing breaks down this process.

2 rotor sets used on the same bike should not be a problem, and should not really increase wear any more than swapping the rotors. You will see increased wear from track use, but not because you do... or do not swap the rotors, but due to the type of use.

There really should not be any "seat" time on pads unless the rotors have been damaged with worn in groves due to trapped particles and trash.

I would say... inspect the rotors and make sure they are both smooth and with in min. thickness specs. If they are, then don't worry about swapping rotors around between wheel sets.

I will keep that in mind as I look for options on this. Thank you!

I did wonder why the bike rotors don't seem to wear like car rotors, and why it's recommended to sand the rotors when switching to a different type of pad, like going to sintered over stock pads.
