Hey I've got a Gary Fisher Wingra (equivalent to Trek 7.2FX http://www.fisherbikes.com/bike/model/wingra) and love it. I've lowered the handlebars so I can lean forward more when I ride, but in strong winds, it's really hard to bike. I'd like to get lower like I am on a road bike to be more aerodynamic.

I've seen bar ends put on the middle of the handlebars to extend the reach of the arms. What kind of bar ends should I get to achieve this goal?
