I tried some swept-back bars last year and didn't like them. I've decided to give them another chance. The bike they're going on is used mainly off-road, with a lot of short, steep climbs and descents. The surface is crushed limestone (not MTB trails).
I'm wondering when I grip the bars where my hands should be in relation to the front hub, head tube / stem?
If I'm too upright I think it will be difficult to climb out of the saddle (I remember it felt hard to get the leverage, but that was a different handlebar than I'll be trying). If the bars are too far forward, well I may as well use the drop bars I'll be swapping out. I love drop bars, and would ride them on this bike in the winter when it's mainly a road bike, but on the trails (April to November) I want something so when I'm riding around my body (back, arms, head) are in a better position, in particular with the descents (when I'm riding the drop bars down a steep hill, I'm tilting forward of course and when I raise my head it puts stress on my cervical spine, which is a pre-existing issue).
