Looking for a 6 bolt to center lock solution

[eggdog]

Just got a sweet deal on some xtr brakes and center lock rotors. I have 6 bolt hubs. Where do I find a 6 bolt to Center lock adapter to fit the rotors...I see there are center lock to 6 bolt but can't find the adapter to accept my center lock rotors.

[Dan GSR]

i don't think it is possible

[cobba]

It's physically impossible to mount a centrelock rotor on a 6 bolt hub and keep it in the correct position where it'd be centred in the brake caliper and it wouldn't rub on the fork or frame.

Just get some 6 bolt rotors. Sorry.

[Stevoo]

Anyone have a chance to get their hands on a new Shimano Saint heat sinked rotor and maybe set a 6-bolt pattern rotor over it to see if there is enough material to machine the 6-bolt pattern into it?

I ask this as I know the Saint center lock has a larger than std center loc diameter and I have yet to get my hands on one and am wondering if there is enough material there to do this.

If anyone has the two rotors and can do this and take a picture that would be great.

I guess any Saint rotor would work for the test. The larger dia hole is the concern.

The new Saint super duper heat sinked rotors are currently only available in the Saint center lock style.

Thanks

An interesting solution to a problem that may not really exist....

Have you been experiencing fade issues that makes you feel the need for the finned saint rotors for larger cooling capacity? Personally I would not bother with the time/cost of machining and just use a pair of the ice-tech XT rotors

Look at how thick the centre or this rotor is.



If you did drill 6 holes into that rotor would it seat on a 6 bolt hub in the correct position as a 6 bolt rotor would ?

Would it line up with the brake caliper as a 6 bolt rotor would ?

Would the modified rotor rub on the frame or fork ?

I'd say the answers to those questions would be NO, NO and probably YES.

the offset is probably different

[Dan GSR]

you are also assuming the aluminum center is perfectly flat

[cobba]

Centrelock rotors are definitely offset, you can see how much a 6 bolt rotor is packed out on the centrelock adapter in this photo and this photo.

[jochribs]

I like Centerlock, actually, I'll say I prefer it. But I don't know why you'd want to try and retrofit a centerlock rotor to a 6-bolt hub. They do make Icetech rotors in 6-bolt. Is there any difference between a Saint rotor and an XT or an XTR? Aside from a few grams?

*edit* I see there is a difference with the Freeza stuff. Sorry. I suppose now is not a good time to say, get some centerlock wheels?

The wavy "fins" on the inside of the brake track

So you are saying it may be possible?

No.

The centrelock adapters simply show how much the flat 6 bolt rotor needs to be packed out so it'll work with a centrelock hub.

The centrelock rotor isn't a flat rotor, it doesn't need packing out to fit on a centrelock hub like the 6 bolt rotor does.

Drilling 6 holes into a centrelock rotor and putting it onto a 6 bolt hub would be like putting a 6 bolt rotor onto a 6 bolt hub but putting about 10mm of spacers between the hub and the rotor.

I know - I apologize my post was supposed to be sarcastic.....

[jochribs]

It's a bummer for the 6-bolt guys that Shimano isn't offering that rotor in 6-bolt. Maybe in the future? It seems logical that those wavy aluminum extensions would really help radiate heat.

You have only two choices:
Get 6-bolt rotors
or
Get wheels with Centerlock hubs.

Does anyone have the Saint center lock bore dimeter? The new Saint Bore is bigger than standard stuff. I will surf the Shimano site when I get some time to see if I can get the actual dimension. But, if anyone knows offhand that would be great.

That dimension is all I need to determine if there is enough material there so I can get the Saint super duper heat sinked rotor to work easily with 6-bolt. Otherwise I will have to go to plan "B" which is to machine a new carrier.

The thickness of the carrier not an issue as I can machine that as needed. It is good that it has lots of material to work with. It is just the bore diameter that is the concern.

Not interested in building a new wheel with a Saint hub as it will be used on a mountain tandem. My Chris King tandem duty hub with stainless steel drive shell is the right hub for this purpose and has been holding up well for a number of years now.

Guess I just bite the bullet and buy the rotor and do whatever I need to do. Just wanted to see if it was a simple quickie modificationn or a bit more involved.

No offense intened but I do have options other than what Shiggy has posted. Making stuff is always fun provided one can find some spare time. Sounds like new carrier it is.

[cobba]

Small centrelock spline = 35mm
Large centrelock spline = 47mm
6 Bolt BCD = 44mm

Post some photos of your handiwork when it's done.

+1 on that.

Cobba,
Thanks for the spline dimensions.

The original Saint CL was 47mm spline.

The current Saint CL is the same 35mm spline as everything else.

Machine the new carrier. I would not trust a drilled stock carrier on a tandem, or even a single mtb.

[Kanik]

Yeah, Stevoo, there was an older centerlock spec that's no longer used. If it's new and says Centerlock, it works with center lock.

Yes, the Saint hub lockring is different. Shimano uses a HG splined lockring for QR axle hubs, and a 16 splined external BB lockring for thru-axle hubs. It is only the lockring that's different.
