You did not mention what your intent was to get the aero bars. Some get them who ride long distant and would like more options of position while riding the bike. It will also help with fatigue and allow you to be more efficient on the bike. Others want them to do short triathlons. The ones you have picked out are fine. Now, keep in mind, some carbon road bars do not allow for aero bars due to the chance of breaking or cracking the bars. I tend to advise folks who have carbon bars to shy away of clip on aero bars for that reason. If you have aluminum bars, you should be ok. Just mount as described my manufacture directions.
Cheers
