Bar ends
I don't like them for three reasons- 1.they weigh more- 2.they can hook a bush or vegetation and crash you- 3. I found if I was riding with one or both hands off the bars and needed to grab the brake lever, It took longer because you need to stab your hand inside the bar end to get at the brake-I found the good qualities of bar ends were outweighed by these 3 reasons and stopped using them long ago.
