centerlock rotor is a little loose on the hub?

[mitch....@gmail.com]

Test-fit a new Shimano centerlock-to-ISO rotor adapter on a new Shimano centerlock hub and there is about half a millimeter of side-to-side play even with the spacer in place and lockring almost tight.

Maybe when I torque the lockring it will tighten up a little more. 

Is this side to side play intentional for a little rotor self-centering float? 

Or will it grind up the centerlock flange if I try to ride it this way?

Also, what tool tightens the Shimano centerlock lockring? I doesn't seem to use any Shimano lockring tool I'm familiar with. And the thin insubstantial seeming lockring doesn't seem to have the beef necessary to torque to 40nm as indicated on the lockring. 

ISO is simpler.

thanks,

Mitch

Centerlock lockrings are locked with the same tool as a Shimano hyperglide cassette.

It's an awesome system once you've used them.  There should not be any play.

Huh. The Shimano item I bought has a smooth inner circumference without hyperglide tool notches and it fits slightly loosely on the Shimano hub. I chose this one because I expected good Shimano to Shimano fit. 

Description text says: "It includes a six-bolt washer, a lockring, and a circle clip to secure the conversion, and a standard Shimano lockring tool is all you need to install it."

That doesn't match the photo.

Maybe someone will recognize what this one is for. I see now that the other adapters pictured do have the hyperglide notches visible on the lock ring.

The first review on the linked Amazon page says:

"IMPORTANT: you must have a bottom bracket tool for hollowtech II or other external bottom bracket tool. This tool is required to tighten the lock ring (pictured on the right). I purchased the BBT-9 tool from park tool for this purpose."

Thanks Bill. I should have read the reviews! Or just looked more closely at the photo. In the meantime the text description on the item is still incorrect. Arg

Yeah, that's just bad information. FWIW, I NEVER use Amazon as a source for information; only to buy things that I've already researched elsewhere. 

Shimano/SRAM cassette tool for QR hubs and the Shimano/SRAM BB tool for thru axle hubs and corresponding lock rings (which is what's pictured). How much did you spend on the adapter? Why not just use a centerlock rotor?

Turns out it's more my fault since I'm just not very aware of newer bottom brackets. The Hollowtech II lock ring tool this adapter uses is in fact a "standard Shimano lockring tool." 

After realizing this (which I would have known if I'd read the review Bill pointed out) I can see why it's better to use this Hollowtech II lockring tool rather than the Hyperglide lockring tool: the only complaint I've heard about the centerlock system  compared to ISO is that sometimes the lockring loosens up and you have to tighten it. The Hollowtech II shape allows you to use an open-ended lockring tool that doesn't require removing the wheel. Not really possible for the Hyperglide lockrings. 

thanks,

Mitch (using an adapter because I already have ISO rotors that came with the brakes. Now that I understand what's going on it all went together properly.)
