I'm thinking of having a custom frame and forks built. I am planning to part the rest together myself. Actually, with the help of a friend.
I have done the online custom fit calculators and talked to a couple of popular frame builders. I have also talked to a few LBSs. Everyone’s opinions vary about the geometry of the frame. And most places want a good deal of money to do a REAL fit and geometry. I get that people need to make a living, BUT, I'm not sure whose opinion to take after getting varying ideas.
I am very tall and have proportionately VERY long legs. I am new to biking this year at age 58. 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, 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?
