I always believed that when bar ends were "invented" they used to actually fit in to the bar ends and locked in place with a central allen bolt, a.k.a. like a quill stem. Is this right ? Or wrong ? If it is right, can you still get them ? I see these have a locking grub screw on the circumference, how would I get on with these with either type of bar end, does the end cap come out ? The reason I am asking is that the bars on my new(ish) commute are approx 2" narrower than my 1st bike and I always felt less "jittery" on that one, I don't want to narrow the bars any further by clamping bar ends on. It's amazing what you can do with an extra couple of inches !! Finally (thank god you say !!), has anyone ever hung bar ends upside down to get a bit of drop in the downhill situation or is it better in the standard position for getting up-hill.
