I am very tall and have proportionately VERY long legs. I am riding a 64cm 1970's Raleigh and with the seat stem maxed out it's really not tall enough. The top tube is 60cm to flat bars extend forward and the reach seems o.k., except my toes are very close to the front tire on turns. I also have 165 cranks and think I need longer cranks. I also wonder about the overall length of the frame hub to hub.
What is the best way to figure up a proper geometry drawing to take to a builder when I get so many opinions?
