Are centerlock and 6-bolt disc mount wheelsets interchangeable?

I'm thinking about getting a second wheelset for my road bike, which came with wheels using 6-bolt disc mounts. If I want to be able to easily swap between wheelsets, must I get 6-bolt disc mounts or can I opt for centerlock? I'm wondering if it'd be simplier to go with centerlock since I'd be buying new rotors anyway, supposing I got a wheelset that had centerlock mounts and required the use of adapters to use 6-bolt rotors.

I do. So yes. You can shim one to align it with the other, if necessary.

Thanks for the quick reply! I recall reading about people using shims like these: https://www.jensonusa.com/Syntace-Disc-Rotor-Shims . They look to be for 6-bolt rotors, so I would use them on my original wheelset? Seems like there aren't many options for shimming centerlock rotors, though I spotted this: https://novemberbicycles.com/blogs/b...sc-rotor-shims

Do people generally not have alignment issues between different centerlock mount wheelsets? If so, that'd be a good reason for me to choose CL over 6-bolt.

In my experience, I can have alignment issues with the same wheel-set.

Center lock is better but more expensive. I would get it (and did for my second wheelset, which was from November, BTW -- White Industries. My 6-bolts are Chris King.). Re-aligning the calipers isn't a big deal. I am pretty sure they make shims for both types, but I have shims for the 6-bolt.

I run both as well and need to shim my centerlocks but I haven't bothered. I don't swap wheels that often and realigning the caliper is easy enough.

x2

I even have a bag of rotor shims in a box somewhere, and just never felt the need to install them.

With the talk about shims, the design is such that the brake rotor position (relative to the caliper mount) is SUPPOSED to be universal, right? I get, of course, that there are manufacturing tolerances and all of this, but with the prevalence of a number of different disc brake specifications (rotor mount specs, IS, post, etc), the one universal standard is supposed to be the rotor positioning "depth" on the wheel, right?

Yes, it is supposed to be. But trivial things, like how tight your cones (or equivalent) are, can change things 0.1 mm or more.

I replaced my 6-bolt OEM Giant wheels yesterday with Hunt Aero Light Disc wheelset and Shimano Ice-Tech SM-RT81 centerlock rotors. Surprisingly, I didn't have to do any adjustments to brake alignment. Shocking even, since I usually need to adjust them even when remounting my old wheels. I mounted and remounted the Hunt wheels a few times and didn't encounter any rub.

I have a similar situation: 2 sets of wheels for my gravel bike, 1 set with 6-bolt rotors and 1 set with centerlocks. When I swap wheels there is enough of a difference that I have to re-align the calipers. Minor pain in the butt, but it is a good opportunity to inspect the calipers and pads. FWIW, the 6 bolts are ROL wheels and the centerlocks are MASON/HUNT wheels.

One trick if they are rather similar in spatial position, but not perfect, is just to jam a wide-blade screwdriver between the pads and twist it to push the pistons back into the calipers a bit, and then you can reset on the new rotor with a few hard squeezes.
