Tips for use – Lubricate / oil screws or dry assembly?

  1. Torque spanners should not be used to open stubborn screws. A torque spanner is a measuring tool and should be treated accordingly. Otherwise the spring may become misaligned and the tool inaccurate.
  2. A torque spanner should be stored at 0 Nm. This way the spring is not permanently tensioned and the tool is protected.
  3. Special care should be taken with carbon frames. Look carefully or read the manufacturer’s instructions to be on the safe side.
  4. Use a screw lock (e.g. Loctite) to secure screws, e.g. on handlebar and stem clamps
  5. Carobon or titanium components must not be lubricated or greased. Special assembly pastes are used here.
  6. Experience shows that a lubricated screw can be tightened more firmly than a dry one. Therefore, tightening torques are given for a dry condition. If screws are oiled, it is advisable to reduce the recommended tightening torque slightly.

This focuses on getting the chain totally clean and dry (no water, degreaser, or lube) before re-oiling it; and then on removing as much excess oil as possible. The end goal is a very clean chain with just enough oil–excess oil will quickly attracts grime. Cleaning: First the chain gets a wipe-down with a damp…
