Centerlock vs 6 bolt disc question...
I am sure this is probably a dumb question, but I'm new to the world of disc brakes...
My current bike has 6 bolt discs. If I get a new set of wheels with centerlock, aside from having to buy the different discs for the wheel and making sure they are the same diameter, there shouldn't be any compatibility issues right?

There shouldn't be. I have one wheelset of each for my main ride.
In practice, the rotors might sit in a slightly different position in space, relative to the bike frame. You can buy rotor shims (usually for the 6-bolt) to correct that. I think there might be rotor shims for center-lock, if you need those instead.
The worst case scenario is that you have to adjust the position of the caliper slightly after a wheel-change.

If you want to continue using your current 6 bolt rotors or you want to buy another set of 6 bolt rotors, you can get adapters for using 6 bolt rotors on centerlock hubs.

wgscott is right -- the design specs would put the rotor in the same place, whether it's 6-bolt or centerlock. If one rotor has worn thinner or is off in some way, you'd just adjust the caliper a hair.

What you want are CL wheels. You can get an adapter for 6 hole but nothing is available the other way around

BTW it is not a stupid question at all. The answer is under-documented.

In case you wanted a real world example, I swap out CL and 6b discs with no issues. Go for it!
