Sadly we don't have this in stock to check,

Will this fit into a 22mm bore of the steerer tube?

Thank you for your enquiry, no sorry it would not fit
Correct torque ?

Got one of these from all and looks good, should be simple to install, but no guide and could not find one on the pro website. Simple question, what should the expander plug be torqued up to? I've done to 5NM, but I'm not convinced that's enough. Not the top cap bolt of course :-)
Hi there,

There is no predetermined torque for this part, it would be just a case of doing it up tight enough so there is no play. A couple of online forums say that 8NM is suitable, however, we cannot be certain I'm afraid.
