I am not giving advice at all... HOWEVER. In my town, of you have aero bars on a NON TT bike.....
#1 You will be dropped on purpose
#2 It will be hard to find a riding partner (unless u can smoke most of them)
#3 For some reason, in my area, people thing you are a poser with them.
Save your back, just go ride. The added weight is not worth it. (to me)
Personally, I think they do not fit a non TT bike.
Too many times, I have heard...while group riding and meeting a person with them.....
"Man, I gotta get me some of those cool looking aero bars"
I have even seen one get invited into a group and the group dropped him on purpose. (I waited on him because I could not maintain the upped pace.
Get them if you want. But if you want to get faster done get the lay downs, just add a few more hours in the saddle.
Good Luck.
