Hi busyone,

I'm the same height as you and I've ridden both. My first bike was a 47cm with 650c and then I upgraded to my current bike which is also 47cm but with 700c. To be honest, I did so because my new bike came stock with the bigger wheelset. It took about 2 weeks to get "used" to the bigger wheels. To be honest, I really hated the bigger wheels but whether it's true or not, it's helped me stay in the pack longer!

I really liked the acceleration on the 650cs and obviously lighter wheelset but eventually found my groove on the bigger wheels. I have a bit of a toe overlap but I've never crashed because of it. And 700cs don't look funny on my bike!!!

At the end of the day, go with what you are comfortable with what fits and what you feel more comfortable with.

Good luck!
