I posted this on the road forum but I was also directed here.
I'm looking for someone that does relatively inexpensive frame work. I want to get a Calfee Dragonfly with my custom geometry but I want to get a "test" frame to make sure I like it before I drop the 5 grand i need for the Dragonfly. Riding a fitting bike and actually going out and riding the built frame is completely different.
Also the geometry question. I brushed up on my trig and think I got it right but hoping someone can double check my work.
My current bike has a 56cm c-c top tube with a 73.5 degree seat angle. I want to slacken the angle to 73 so I can get more setback w/o getting a special seatpost. Changing the angle will change the top tube length right? I don't care if the seat tube length changes but for reference, its a 56 c-t (cannondale). With my calculations, I came up with 56.5 (rounded up)
