Evening all.

Just a quick question. I've got some Shimano.SM-RT64 centrelock rotors on my bike.
Does anyone know which tool.I'll.need to remove /install , as the standard cassete tool doesn't work?
I'm thinking possibly the Shimano bottom bracket tool is what I want, but I'm not 100% sure?!

Same as a cassette lock ring tool if you have one of those? Edit, somehow read past you saying the cassette tool doesn't work.
This then, older / trad external cup BB tool >

A old shimano or other external BB tool also works, on the outside of the lock ring.

I have a casette tool that does not fit so had to buy another to do this ( has a centre pin on new one)
Newer rotors use the bb size outside/ external but are much bigger than the casette type ( internal ) and does look pretty much like a casetter bolt and sounds like what you have.

Is it the eternal or external splines on the locking?

I'm guessing internal, if you're using a cassette tool, and that your problem is that the axle end cap is blocking the tool.
Can you get the end cap off?

It's an external spline lockring

I had to resort to a splined locking and something like this...

...to fit rotors over my end caps

We mean does the.tool grip the outside( bb tool) or inside of the lockring (.caseete tool but not all.fit IME)

Looking at Shimanos tech docs for that rotor, the tool you need is the TL-LR15

This is a standard cassette lock ring tool, not sure what you currently have that doesn’t work.

I bought a ParkTool BBT-69.2 for doing external splined lock rings; meant I could stick the torque wrench on them. Seems to be discontinued though...

That’s not the tool needed though, I linked the Shimano document in the previous post for the specific rotor he has - the part number for the tool needed is shown in the doc (It’s a cassette lock ring tool).

I have Shimano rotors, they're not held on with the Shimano lock rings. Beside, they said that it's an external spline lockring. For the avoidance of any more doubt:

External:


Internal:

That’s not the tool needed though

Last two centrelock rotors i bought did not come with a lockring so its not 100% definite what its locked with ( and either would work )
based on what the tech doc says.( more likely poasibly, vut certain , no.)

Specific rotor type/make doesn't matter, just the lockring used. If external as below then yes, just a bb tool. Type of lockring is just down to axle/end clamp clearance right?

I think qr were centrlock internal/ casette tool then it changed to accomodate bolt through, but not 100% certain.

Ah, I’d missed that!
