what part were the wrench settings on – the stem i hope.
because theres no such thing as a clamping torque imafraid.
a clamping force depends on the tollerances , the surface area and the force applied via the bolt.
So handle bars cannot have a torque value on them – how does the manufacturer know what stem your using.
The stem can have one as the designer knows what his clamp area is , his tollerance and the bolt size – to give a safe grip pressure for a given torque.
IME if you torque up to the torque value given on ANY ritchey componant – it WILL slip regardless of fibre grip etc.
Onto another point – carbon bars are less tollerant of point loads from sharp edged stems – which sadly even from high end manufacturers still exist due to manufacturing processes.
I tend to take sharp edges off with a light file before fitting with fibre paste and trying at the suggested torque – if it doesnt work i up it by a couple ft lbs till it does stay solid. Remember engineering process and fear of lawsuits means theres always a safety factor.
*Never had a carbon related failure – and have 3 almost all carbon bikes in the house.
