I have an all aluminum low end bike that I bought to get started in Tris last year. I want to keep my road bike but add clip on aero bars. My goal is to upgrade this bike as much as possible and then by a tri frame if and when I continue the triathlon racing. I was surprised at how well I did in my first year and want to get better and the bike is what is kicking my ass@!!!!! What aero bars would anyone recommend. Can I put these on myself or should my LBS help? Should I get a forward placement stem or hold off on that for now?
