any cyclists/roadies?

Just started this year (to start doing sprint tris). Got a trek 1.2. Good beginner bike for me, not knowing how I was going to like it...I LOVE it. I'm already doing my second tri this coming Sat. (my first was July 11th). I may step up to Olympic distance next year, with my eye on a half iron within a few years, and dreaming of being able to train to do THE Ironman...Hawaii.

I've never had a bike this nice before, and I realize that having a good bike makes a HUGE difference in your enjoyment of riding. I'm thinking that I'll potentially do some duathlons, too. The ride on my bike is so smooth. I just need to incrementally upgrade components on it, though. It's a good start, I feel, though.

Question for you guys...when I ride, I tend to get some numbness in the outside of my hand and middle-pinkie fingers. How much of a difference would gloves make? Or would I be better off in getting some arrows?
