I just bought a vintage Specialized Sirrus in I believe 49cm, I literally just got it yesterday. I have to double check of the exact size. I have to tip toe when I stand on it but I feel comfortable riding it... I love it but it may be a little too big for me. It is really hard to find my perfect size in the older models....it's sad. I am enjoying the ride for now... I can always sell it I guess since it is in the shop right now getting tuned up.
