@Stir Fry Make it make sense
I'm about to finalize the plans for my custom titanium bike I'm building specifically for ultra long-distance racing. I have a 250mi race coming up next year and I need something comfortable and fast. I was hoping the top tube would be much flatter but doing so would only add weight. I'm trying to decide whether or not to drop the seat stay a little for compliance or just leave it classic. How did you do your seat stays?
I would trust your builder, if he says 73 degrees is fine, then that's what I'd go with. His experience is what your paying for after all. If he says you can go slacker, I would probably go for it though. 73 is still considered steep and you'll be wanting all the comfort you can get when doing 250 miles in the saddle. 71-72 degrees is more conventional road geo from my understanding.
I wanted my top tube flatter too. Despite what the drawing shows, my TT came out with a slight slope to it. I've gotten used to it, though I still wish that it was as parrellel as my old frame was from time to time. The comfort far outweighs my slight nitpick on the aesthetic issue however. My seat tube is 75 degrees and is tuned for 50+ mile rides fwiw, and I come home without any aches afterwards.
Congrats on the new frame, custom builds really do make a world of difference, especially at the end of the ride lol.
