Dear Lennard,
At the risk of re-opening the ‘greasing the Campagnolo BB spindle taper’ debate, do you recommend greasing the hirth joint teeth on the new Campagnolo Ultra-Torque cranks? The instructions are a bit vague on that topic.

Dear Ned,
According to Campagnolo: “No grease at all. The instructions don’tspeak about it because it’s not useful to grease the teeth of the Ultra-Torque crankset.”
