There's another factor to bar comfort that a lot of people don't think about and that's the angle of your levers. A lot of people set them too horizontal - - or angled properly for when they are seated. But adjustement should be for your agressive standing position for descending (especially if you're a downhiller and you 'cover' your brake levers a lot). Standing situations are where you're going to need your brake reach the most; and if your levers aren't adjusted for that, your wrists will fatigue much quicker. Just a thought . . . .
