greasing Campy crank bolts(4 posts)

greasing Campy crank boltsDaveG

I just finished building up a new frame (Torelli) with Campy Centaur10. AFTER I put the cranks on, I noticed that the Campy instructions said "never" to grease the crank bolts. Before reading this I always assumed they were to be greased which I did. The bolts did have some type of Locktite-like blue stuff on them. Did I make a make a heinous mistake by greasing the bolts? Should I pull them off and clean off the grease? I am a worrier so this will bother me until I get an answer. Thanks

It's too late to worry about it now. As long as you don't exceed the recommended torque or repeatedly retighten the cranks, I doubt you'll have a problem. The most commone mistake I've seen is repeated tightening. Some people retighten the cranks every week, until they manage to stretch the internal taper and mess up the chainline. I put cranks on with a little lube and rode for two years without touching the bolts.

I've heard it both ways. I pulled my cranks and bottom bracket for the first time this weekend. The shop that built it up did so with grease on both. Campy says no grease on BB or crank spindles. It worked for a year so I regreased them. I don't know what the downside is I have always used grease in both areas with no problems.

The reason they say this is that they put a pressure-activated LocTite like stuff on the threads, and grease destroys its effect. It's to late now, but no harm, no foul. LocTite is for when you don't properly tighten the crank bolts. Assuming you know how to do that, you're good to go.
