I have used Phil’s grease pretty much since getting back into riding and building in 2015. I’ve had my LBS help rebuild BB’s and hubs and had them use Phil’s on request. For what it’s worth, me being 215# and riding 700x35 Rene Hersé Extralight tires, my Italvega Super Speciale rolls down hills from a standing start faster and farther than my vintage groups’ bikes. I use Campagnolo Nuovo Record hubs almost exclusively and new bearings. So far in 5 years of riding, the BB spindle, bearings, and cups look fine. But they do get rebuilt every year.

I lucked into a deal and got 4 unused tubes of Phil’s grease for $20 from an Offer Up seller a while back so I’m probably set for life.
