I am just starting to do sprint triathalons. I am mostly a runner. However, I have really enjoyed them so far and am looking at investing in a new bike. There is a ton of information out there. I have looked into TREK WSD 1500, Giant, Motobecane Elite Gigi, and Windsor Willow. I am female, 5'6''. Don't want to spend a ton. Any opinions would be appreciated. Thanks!
