My road bike has a more upright handlebar position, with a 25deg stem (110). When I bought the bike used, this was the best solution to fitting since the steerer was already cut. I really can't handle the extreme drop position that a 0 or 6 degree stem would offer on that fork. Anyway, I just bought a new fork, and I'm trying to decide how best to configure the stem & steerer length. I want the handlebars in the same exact location relative to the frame, but I could add spacers and go with a shorter low angle stem to achieve this setup. Is there any mechanical advantage/disadvantage (i.e. perhaps less/more stress?) to go with a shallower angle stem? Obviously, a shallower stem will preserve more steerer length, so that's a bonus. Of course, I would need to replace my current stem. Just wanted to see if I'm missing something ... thanks!

BTW, it's a carbon steerer.
