- Do Shimano 6 bolt and centre lock hubs place brake rotors in the same position?
They *should* be in the same position but only once have I swapped wheels and not needed to adjust the calipers.
The concern with QR XT hubs is that as the cups/cones wear and the locknuts are adjusted the effective width of the hub changes so the position of the fork leg relative to the hub changes slightly, and the calipers will need adjusting even on ‘identical’ XT wheels.Posted 5 years agoandylMember
If the difference is in the correct direction you can use shims on the 6 bolt rotors to space them out to the same as the CL rotors.
However if the 6 bolt sits further out already you are a bit screwed unless you can add a small shim to the QR axle to increase the gap a touch but I guess you have to be careful not to misalign the fork legs.Posted 5 years agomrbelowskiMember
The clearances on my Elixirs are so damned tight that half the time I have to muck about with the calliper after replacing the wheel anyway. I would be surprised if even 2 wheels with the same rotor fixing method (even the same hub) didn’t need some calliper fettling after a swapPosted 5 years agoNaranjadaMember
I want a spare pair of 29er wheels fitted with commute-friendly tyres to swap with wheels fitted with MTB tyres. The MTB rims have Shimano XT 6 bolt hubs.
The cheapest, ready built wheels with Shimano hubs that I can find all seem to have centre lock hubs.
I don’t want to have to adjust brake calipers each time I swap, although I suppose it wouldn’t be the end of the world, an extra 5 mins faff.
Changing tyres is not an option, the MTB rims are Stans and tubeless.
Who knows if both types of hub place the rotor in the same position and so will not necessitate adjusting the calipers every time they’re swapped?
