Bar ends are out of style? Ha! I spit on your style. Just look at this picture that I Google-thefted. It just wreaks of cool(ish)ness and spews style like a volcano.
Now take a look at my bike. 710mm Niner carbon bars + bar ends = all friggin' kinds of leverage and power for climbing. And cool and stylish. You betcha.
I tried removing them recently so I could be like all of the cool kids, but it just plain sucked.
Nevermind the drawbacks like catching them on trailside flora and fauna on high-speed decents. They are too cool not to have. True dat.
