I've been cycling for a little over a year now and I've been leaving the bike maintenance to my boyfriend for the most part who's been riding for years and is all kinds of handy. We're moving at the end of this month and we'll be so close to the bike path that I'll be able to go riding a lot on my own. And I suppose it is also time I learn to stand on my own two wheels

I already know how to change a flat in theory, and plan on practicing a lot in the living room to get very comfortable with it before hitting the path. I can do some other basic stuff, such as adjusting my saddle.

My boyfriend also wants me to learn more about diagnosing possible problems with my bike when I'm by myself and learning how to handle said problems, which is a good idea. He is a good resource and I plan on using him for information, but sometimes written material is very helpful for me. Can anyone recommend some good online reading, or books that provide maintenance info and "diagnostics" as it were?

Thanks so much!
