Centrelock tools

il_principe

I have a new bike equipped with SRAM rotors. They are secured using centrelock with external splines - like this:



Can anyone recommend a tool to remove these? I have 2 tools, neither of which work:
https://ride.lezyne.com/products/1-st-exbbt-soc-v108?_pos=2&_sid=2c7f548c6&_ss=r This is too shallow and won't fit over the protruding axle to engage the lockring
https://merlincycles.com/en-gb/pedros-bb-wrench-shimano-16-notch-99358.html This is too shallow and I cannot get a proper grip on the splines with it.

The only options I can find that looks like they would work are:
the IceToolz Disc Brake Lockring Tool, #M082 https://icetoolz.eu/en/icetoolz-disc-brake-lockring-tool-m082/a5840 but this is not in stock anywhere.

Or the Park Tool BBT-69.4 https://www.parktool.com/en-us/product/bottom-bracket-lockring-tool-16-notch-bbt-69-4#tabbed-section but I'm not sure if this is deep enough to fit over the axle and cannot see any dimensions online.

I can't believe this isn't a common problem but there seems to be very little information online to assist with this. Can anyone recommend a tool to do the job, preferably something made of steel rather than aluminium?

Thanks.

I've seen a video that suggests you can use an external bottom bracket tool to remove the lock ring. This one has a dual function - one of which has 16 notches that would match your rotor lock ring.

Just not sure about the overall diameter of the tool and whether it would fit over the said lock ring.

I've got the Lezyne one you picture and haven't had an issue, but maybe the axle configuration is different and I can get the end caps out of the way or they just don't stick out that much. I've a spanner type tool as well similar to yours but I do prefer the socket type.

The comments against the Park Tool alternative you linked suggest it is deeper in order to fit over thru axles.

This or any other brand that's similar.

I use a bottom bracket tool exactly the same as in the post above.

Drill your Lezyne tool so the axle can go through.

I also use a spanner type BB tool, it works fine, you do need to be careful though as it can slip off if the splines aren't fully engaged.

I have had the same issue.


Get some lockrings with internal splines so you can use a cassette lockring tool. This works better as it isn't dependant on how deep the BB tool is or how much the end caps stick out.

I have discovered that on some wheels the internal spline locking rings won't work so you have to use one with outer splines and use a BB tool rather than a cassette tool.
