Sheldon Brown's vintage technical information site has been around so long now that I mistakenly assume everyone who's into vintage bikes would know about it. But you know what they say about making assumptions! So if your new in these parts or have been living under a rock, check out one of the most extensive databases of tech info ever assembled.



Charts, diagrams, photos, service tutorials, sizing data on everything from tires to bottom brackets - this site is way beyond useful, and possibly addictive. You've been warned.
