I never use a torque wrench on a bicycle. I just can't visualize Fausto's or Gino's or Eddy's mechanics doing that. Tighten to remove all play, then stop. Don't know what Stronglight recommends, but I highly recommend a VERY light film of grease. My usual method is to wipe the grease off my fingers (I've usually been greasing the bearings just before installing the BB axle) with a rag, then rub the small amount of residual grease remaining on my fingers onto the tapers. The ponit is, you don't want to heavily grease tapers as it causes you to drive the arms on further, enlarging the hole. But Stronglight cranks need at least a thin film of lubrication to avoid seizing. Maybe some high tech anti-seize will do as well, I just never felt the need for it.

Stronglight cranks are softer than Campy, which is why they don't crack like Campy NR infamously do. The downside is, they are also more susceptible to seizing. Having hammered seized Strongligh cranks someone installed totally dry off the axle, I highly recommend some anti-seize measure.

Subject line about sums it.

Can someone tell me please, what is the recommended nominal torque spec for the bolt securing the crank arm to spindle?

Can someone tell me, please, if Stonglight recommends applying lubricant (grease, oil, anti-seize) to the spindle taper. This is R&R of previously mated to each other spindle and crank.

Thank you.
