Barnett manual- more mechanical information than you will ever need

Back in the old days in California all the "pro-shops" had a copy of Sutherlands--- even in later years when the mechanics could not read English.

Don't know about "self-taught". Many of those Mexican mechanics had done long apprenticeships and were far from self-taught. I also knew a few Americans that went to trade school to learn metal working and bicycle mechanics. I knew some that crossed over from art.. and at almost every tech shool I attended--- and I'm talking about some of the most highly regarded institutes on the planet--- there was always a core learning to build bicycles. I also knew a few aerospace engineers that crossed over after their layoffs. In Europe bicycle mechanic was long a guilded trade. Even in Holland today you still, I think, need a "master trade letter" to open a shop.
