Thanks for the thoughts. My bar is now about 500mm. And, of course, as you know since you only get one kind of hand position with a flat or even semiflat bar, the bar ends, for me, have been life savers. Particularly as I have a chronic carpel tunnel issue with on of my hands. So, for me, bar ends are a must. Just one more reason for dumping that Trek proprietary flat bar in favor of something a little less.... well, proprietary.
