One thing I disregard is the intervals in which to re-lube.
Some make claims that it's "so many miles" before re-lubing, as if there is a right or wrong to this.
I have been to the TdF and watched the bike mechanics clean the bikes after each and every stage race. Yeah, complete cleaning and re-lubing. But then again, this is a professional race on the single most watched road race.
Saving money: this is not the time to claim that you save money by getting a lube that "saves you money" by somehow working better than brand "x".
Years ago I met the guy who is the distributor of Boeshield. It was at the InterBike trade show in Las Vegas. As far as formula, nothing had changed, it works. Just keep re-lubing and cleaning.
