Centre lock vs. bolt-on rotor

[LazyLab]

Looking to get a second set of wheels but need to be sure about fitment. I have WTB Speedisc wheels with a 160 mm centre lock rotor. Would wheels with a  bolt-on rotor fit into the disc calipers without having to adjust anything?

in my experience almost no two hubs are quite the same. You always have to adjust.

 

..or put the spacers behind the IS mounts on the disc (0.2mm shouldn't change anything..)

i hate hubs. they always seem to complicate things. axle-through, spoke hole, IS, 6-bolt, centrelock, QR, 135mm spacing. DAMMIT! MAKE A STANDARD THING!

We have 2 sets of wheels for our MTB's - mine both have DT Swiss hubs, and nothin n eeds adjusting, the wife's are a combination of Centre Lock and 6-bolt, and the calipers need adjusting between the 2 (I haven't bothered to 'shim' yet, but it's a real pain!

 

On another note, my bike has Juicy brakes, and hers has XT - I find the juicy's easier to get set up right than the XT's

Thanks for the feedback. Is it common that the re-alignment required is as small as 0.2mm? If so, shimming the rotor could be a clean solution!

Tarpon - my experience is that it isn't much (not sure whether 0.2mm, but enough for the disc to 'rub', rather than 'lock' or distort the disc)

 

So shimming is probably the answer - you just need to get hold of some 'shim' material - If you know someone tho works in an engineering manufacturing/maintenance environment, you could probably get some (professionally you can buy it in sheets of varying thiskness - usually a 'brass' type material)

Thanks levett. I also have access to shim material. This should solve the potential interchangeability issues. To find a second set of wheels (with 160mm rotors) is the next challenge!
