I haven't seen anything significant online other than Fred Matheny's page/s. Him and his co-authors at any rate; I don't know who started it up, but Fred wrote a book about bike racing that I think has a lot of good things in it. I know it's outdated but the philosophies are excellent for real world racers. Things like you have to take into consideration work and family when thinking of whether you're "resting" or not, and that equipment that works is all you need.

Beginning Bicycle Racing, Fred Matheny

He now has a site that has a lot of advice. I haven't gone further than the entry page (linked to it) but it should be pretty good. You have to pay for access. Some of the eBooks seem a bit unrealistic to me. $10 for how to travel with a bike? That kind of turned me off. Granted, it may have been written a long time ago, but still, it seems a bit much for something that you could, say, search in BF or in people's blogs (ahem).

A site that happens to show up if you Google my name and sprinting is here. They offer some basic info.

Most resources offer technical advice. How to sprint. How to attack. Almost none offer tactical advice. When to sprint. When to attack.
