With a 73cm saddle height, I get about a 10cm saddle to bar drop with a stack of 527mm, a 15mm headset top, no spacers and a -17 stem. I use a 100mm stem and 80mm reach bars, with a 383mm reach. If I want, just changing to a -6 stem would raise the bars by 2cm. Endurance franes with adequate seat tube length and about the same reach have 2-4cm more stack, so just changing the same stem angle would match some endurance frame's stack and 2cm of spacer would match the tallest stacks, without looking stupid. If I need less than an 8cm saddle to bar drop, I might someday look at an endurance frame. At age 67, I'm not there yet.
