Disc rotor torque setting please

Hi

Can anyone let me know the torque setting for disk attachment to Chris King hubs please?

Thanks

Andy

Do them up with a screwdriver & use loctite. Torque settings would depend on the bolt, not the hub – try the brake manufacturer.

Don't they depend on the application?

Anyway do them up reasonably tight, works for me.

they're Hope

Torque settings are commonly dictated by how much force is needed to stretch the bolt a little, so as to provide maximum clamping force. The reading you'll get from a torque wrench for a given amount of stretch varies according to whether the bolt is going in dry, greased or with threadlock.

Granted in some applications (say, carbon bits being clamped), you're actually limited by how how much force the item can take, rather than the bolt.

The Avid rotor I just fitted at 6.2 (something) marked on it.

I can't remember.

many thanks

Is this the wrong time to say "It's a blinking bicycle, just nip them up tight"

It is, isn't it?

IIRC Hope say 4NM but as said above, Avid are 6.2Nm. I do mine up with a preset 5Nm torque key and I've never had any issues (normally leave the thread lock on that comes with the bolts but even run dry on holiday after packing the bikes, 5Nm has never cause a problem). I think it's more to stop the ham-fisted from stripping alu threads out of expensive parts.

frum memoree 655 lb-in but if u luk on park tulls websight u can chek to b shur

I'd go with 5Nm and threadlok (the blue one). Any more would risk pulling the threads out.

Hand tight – I use a small wratchet screwdriver with torx bit and do it up as pretty tight – I don't use anything with a long lever so will stop you doing it up too tight 🙂
