I think I read somewhere that the chainring bolts take a T30 torx wrench rather than the standard T25 normally used for other bike fittings. Can anyone confirm this? I want to avoid rounding out the bolt!

its a T30 torx plus.

a standard torx will remove it – they are backwards compatible , but a torx plus will be a tighter fit.

Thanks trailrat, you saved my crank.

They aren’t using those on Cranks now are they? Torx bolts should be banned: They are the devil’s work.

Nowt wrong with torx- far superior to hex in many applications.

Monkey paws will destroy anything

Torx is the way forward for me , much nicer to use than a nasty cap head Allen key bolt
Or maybe I should say hex to save upsetting people
