Titanium bolts Help

[wpa1975]

I have Titanium bolts to replace steel and rusty bolts on the Brompton, what should I put on the threads please, grease, copperslip or leave them dry.

I use copper grease / anti seize on mine. Never had a problem with bolts backing out or coming loose.

Copaslip is spot on to prevent titanium from reacting with other metals, although I use Loctite on bolts that really mustn't come undone (e.g. brake disc mounts).

Never loctited anything on a bike in 40+ years,ever had one come undone?

Off topic (definitely not titanium) but I've had the pinch-bolts on Shimano Deore 2-piece cranks loosen and the left crank arm fall off while riding a couple of times, I've been meaning to add some loctite to the bolts to help avoid it happening again.

Just brake related stuff I've always done so caliper and rotor bolts.

My more recent full sus frames have aluminium shock mounts that bolt to the downtube which I've used Ti bolts on, they also get a dab of loctite as they def don't want to be coming loose!

Everything else just gets a dab of slip or teflon grease.

Thank you all, yes I have also used Loctite in the past on crank and brake bolts.

Two things that often came undone without Loctite: Reach adjuster on right hand brake lever (Hope Race), and dropper tension barrel (KS Lev). Sorted with Loctite (blue).

Pivot bolts on full suss bikes definitely need it or loosen off in my experience
