Hey all.

I've been looking to get into the single speed/fixed fear scene for a while now, and I just purchased my first bike.
It's a 41 cm Retrospec with 700 wheels. Upon first sitting on it, it felt right. I'm 5'2" by the way. I seemed intimidated by the bigger bikes at first.

However, after riding about 16 miles with it, my lower back started to feel uncomfortable. By arms also have the urge to be higher.

I am beginning to think I might need something larger. However, the bikes sales people first wanted to direct me to a 43 cm SE Draft with 650 wheels but it looked way too small. I got the 41 cm with 700 wheels.

Would it be too much to ask them if I need a bigger bike?

thanks...
