One thing... if you have a bike outdoors, make sure all screws are either greased, have anti-sieze compound on them, or locked in with a threadlocker compound. I grease pedals, water bottle bracket screws, and most importantly the seatpost. If I had Ti components, I'd use a distinct anti-sieze compound. For the brake canti bolts, I use a threadlocker.
One can argue about the merits of threadlocker, anti-sieze, or grease, but all three prevent bolts from becoming a permanent part of the frame after a while outdoors.
