Grease is a third question.

Are you looking to re-pack the bearings on his bike? Phil Wood grease is popular and ubiquitous. Campagnolo grease is more expensive but renowned for its long life.

Depending on how lightweight his bike and how fine the tolerances in his components are, regular axle grease from the auto parts store - whatever you already have in your garage - might be plenty.

Don't use grease on external parts like chains and cables. Save it for parts like hubs, bottom brackets and headsets that are more or less sheltered from water and grit. A *thin* layer of grease on quick-release skewers is a good idea, too.
