If you travel with your bike, choose centerlock hubs/rotors so you can remove the rotors easily. Otherwise 6-bolt has fewer clearance issues with flat-mounts, especially those on the forks.
For example my White Industries CLDs used 15/20mm lockrings (Shimano BB tool type) and those would not play nice with my Emonda SLR's fork. I had to get White Industries to send me a revised axle/endcap that would allow me to use the regular QR/12mm lockrings instead. Admittedly this is an oversight on White Ind's part, but it's a thing that happened.

Except that then you need to also travel with the appropriate lockring tool and a minimum 8" wrench to get sufficient torque when installing the rotor. For the six bolt rotor all you need is the Torx or allen key.TobinHatesYou wrote: ↑Fri Jan 04, 2019 1:08 amIf you travel with your bike, choose centerlock hubs/rotors so you can remove the rotors easily.

If you are going to have multiple wheelsets then I think 6-bolt is maybe a bit better since you can easily space the rotors so you don't have to adjust the caliper position when switching between wheelsets. I have both King R45 and DT 240S hubs in centerlock and the rear hubs play nice in terms of spacing but on the front I have to adjust the caliper position when I swap wheels. Not the end of the world, but with 6-bolt it could be seamless.

I have 4 sets of wheels... all centerlock with different hubs .. so far I'm lucky.Bigger Gear wrote: ↑Fri Jan 04, 2019 2:56 amIf you are going to have multiple wheelsets then I think 6-bolt is maybe a bit better since you can easily space the rotors so you don't have to adjust the caliper position when switching between wheelsets.

There are really no side forces to worry about, so you don't have to go to the insanely conservative 40n-m recommended torque. The lockring is not going to back out.

I'd much rather pack this tool than waste time with 12 bolts. For a non-travel bike, I don't care...both interfaces have pros and cons.

Centerlock. Much easier for me. 5 less things to torque to spec.

Funny you say that, because I had the exact opposite problem on my Concept Disc, the bolts on the rotor would hit the inside of the fork where the flat mount disc caliper is mounted when sprinting, so had to rebuild the wheel with a centerlock hub to get better clearance. So now I run both...6 bolt on the rear, centerlock on the front, mainly because I was too cheap to swap out both hubsTobinHatesYou wrote: ↑Fri Jan 04, 2019 1:08 amOtherwise 6-bolt has fewer clearance issues with flat-mounts, especially those on the forks...
