Do Centrelock rotor...
 

[Closed] Do Centrelock rotors sit further outboard than six-bolt rotors?

Building up a new frame (PX Stelvio), all good apart from some rotor clearance issues on the fork.Using a wheel with a Deore Centrelock hub, the 160mm rotor fouls the caliper mount (using BB7s). I can use a 6-bolt FSA-hubbed wheel fine as the rotor sits slightly more inboard.

Is this greater outboardness a general issue with Centrelock rotors?

Nope. I have a mix of centerlock and 6-bolt hubbed wheels for my Amazon and can adjust between them with little more than a tweak to the pads - also BB7s btw.

Is it a brand new Deore hub?

No. However the problem will be that you have cup and cone bearing hubs, and the entire hub will be offset. This is easily rectified by adjusting the cones and locknut on both sides of the hub to shuffle the hub body across by a MM or two. You'll need cone spanners to do this..

Ta. Looks like I'm just unlucky with the combination of hub/rotor/mount. I have another 6-bolt wheel that I can put on it (as the one I'm currently using was quickly nabbed from my wife's bike just to see if it worked). I guess I'll just have to measure it and see.

Snotrag - how would that work? Surely I'd just be shuffling the axle through the hub, so there'd be a bit more or less in each dropout. The relative measurement of the rotor to the mount would stay the same?

I will accept any dimness on my part...

^ +1 - just so happens I have a Deore hub on my desk at work and the axle can move through the hub but the width of the dropout faces and their relative position to the hub body are fixed*

* within reason - you might squeeze a tiny bit by graunching the cone in tight but that'll muck up the bearings. And you could conceivably fit spacers between but IME you shouldn't need to.

Yeah, snotrag is talking nonsense there ๐Ÿ˜‰

This is probably a silly question, but we've all done something like this: is the rotor the correct way round? Just in case it's not quite central on its base, if you see what I mean.

Yep, rotor is on the right way round (that was a "are you sure you're not being stupid" check I'd already made ๐Ÿ˜‰ )
