I got my first road bike in March, 2008.. a 47 cm Trek 2.3 WSD. I really loved it (still do), but as I got more accustomed to riding a road bike, I realized I felt cramped in it... I then saw a video of me riding it and I looked cramped as well. So, in July, 2009 I got a 50 cm Trek Madone 4.7 WSD. I love this bike and feel so much more comfortable on it and I have had many joyful rides on it. But I know in my heart of hearts that it's not my last road bike !
