a fit aquaintance is looking for a not expensive (<$1000) multipurpose around town bike and I was thinking of helping him build up a simple around town bike with bars about 1" below the seat . It seems that most 62cm production frames have 24" top tubes, is that long enough for you tall folks? I was thinking something like a Surly Karate Monkey because it's sturdy and the high bb would be good for 180 cranks and the effective tt is almost 25". Setting it up initially as a one speed to keep cost down. Are there 62cm bikes/frames you very tall people have found are big enough?
