6 bolt or centre lock rotors

[rudi-h]

Ok ok. So what about this then?

 

shhooo

 

not much thought gone into that design...  i can break that setup it in 10 different ways in as many minutes...

I never noticed any performance difference between them. As mentioned before, you get adapters if you feel the choice of centre lock is too limited.

 

Me, going forward, will favour 6-bolt hubs, but it's not a deal breaker.

 

Btw, "bolt" is a strong word. I'd rather call the teeny little screws. It's Friday peeps!

I have worn splines on my one (last) centrelock hub.

Centrelock is crap.

Most probably because it was not tightened to the correct torque settings. Movement, even minute, will damage splines (any splines) quickly.

I've been using mine since 2009, not a days problem.

i like 6-bolt: any fear of shearing off due to braking forces is utter nonsense. Too long down the road for that kind of silly thinking.

 

It can be a pain some times, in that if you don't anti-seize them, and/or you don't periodically loosen them, they can pretty much seize, requiring the head to be drilled. But that's few and far between.

 

There's redundency in those 6 bolts: lose one or two on one wheel? No problem, grab one from the other.

 

Them bolts come in lots of funky colors and shiny, titanium. Centerlock is utterly fashionless

Ask that cake how far he goes if he buckles that rim a little bit.

Ok, so it is not a rumour. Obviously this could have happened because it was not tightened correctly like Wannabe mentioned. A 40Nm setting for these centre locks is pretty high, my torque wrench only goes to 30Nm, so it ends up to be a guessing game if you have under or over tightened it. 

I can't trust bike shops to set the correct Nm, so they could have introduced the play unbeknown to you.

Probably ja. Got them second hand.

The movement obviously exacerbated over time as well as the splines wore out.

6 bolt all the way. Why make something more complicated than it needs to be?

Yeah, I think I will go six bolt, at least I don't have to buy any special tools to work on them.

I tend to agree - I have used both and my wife's bike still does center lock. One disc came loose once because it hadn't been tightened properly. Never again. The only reason for having center lock however, is convenience. Doing six bolts to change a disc takes ages in comparison to using a cassette tool...

Same as cassette tool. If you are going to tinker with your bike, one of the first things to get is a chain whip & cassette tool.

And it literally takes only a few minutes to change a rotor with the center lock system.

And you can still buy the "cheaper" 6 bolt rotors to use, if you have the adapter as in my previous post.

To me, best of both worlds.

I've only had to change a rotor 3 times in 5 years, and the time required to undo and then redo those 6 little bolts isn't much. Compared to the time spent cleaning and lubing those hundred-odd little chain links every other ride...

 

My biggest worry is stripping the bolt head with a badly fitting torx bit, but the bolts that came with my Shimano rotors are pretty tough.

 

Perhaps also relevant which hubs are more available?

You can always replace the torx head bolt with something else, like allen cap or whatever. Don't like torx myself.
