Sounds like you know what you're up to.
In contrast, I'm just learning how to take care of my bike properly and in reading my Zinn book found a section devoted to measurement for getting the right frame dimensions. I haven't gone through it yet, but as someone who is also long of leg and short of body, I have found that many bikes don't fit quite right, and I'm hoping that following the measurement advice from the Zinn book will help me specify what I need out of a frame and its accoutrements.
