torque pressure for tightening quill expander bolt on top of stem
Whats a general ballpark figure for reasonable Nm pressure to be applied to the quill expander bolt on top of stem?
I have a cube hybrid/fitness bike and being a tinkerer i losened this at one point to see what i need to highten the stem.
Its now tightened with a simple allen key by hand, not too tight and erring on the side of caution and its been like this without issue for months, but ive gotten access to a torque wrench so just want to give it a touch with that to ensure its tight enough.
The cube website helpfully tells me to never touch this bolt and only let a specialist shop mess with this part of the bike (if we didnt mess, how would we learn anything?).

Owning a torque wrench is required in order for "how tight" to be communicated with an internationally recognized standard number..

Alloy quill stem inside a steel steerer tube / steel fork OR threadless stem clamped to alloy steerer? Makes a big difference, bad accident if a quill stem gets loose.
