On your crabon bars?
Torqued to precision of course.
Crank it up until you hear the carbon crack and then back it off a quarter of a turn. Job done.
4nm, below spec for bars/stem but more than enough to keep em in place with carbon paste
Wondered if 4nm was the sweet spot, confirmed.
5Nm as per the writing on the bars and stem.
5Nm seems pretty standard for carbon parts and is the preset value for my torque clicker
Renthal apex stem here, no specified torque writing on stem, went 5nm
Does a knurled carbon surface work the same as paste?
Forget paste, try without first then torque to between 4NM and 5NM as standard.
some stems require 6NM
5nm, using my calibrated Norbar torque wrench.
Knurled? never seen that on carbon bars (But I've only had 3 or 4 different brands tbh), tbh it would put me off, as it could provide plenty areas for crack propagation.
I guess he means roughened, not knurled.
Crank it up until you hear the carbon crack and then back it off a quarter of a turn. Job done.
Oh yeah, this works every time for me too. 😉
Thomson bar and Thomson stem would not stay put at 5 Nm no matter what
They are now quite tight - not cassette lockring tight more mech mounting bolt tight - and they've been fine
