i ride 46 16 right now but have a new setup in line. it will be 48 16 which is nice since i used my bike mostly for commuting. I have ridden a setup as low as 39/17 which was fun, but not good for going across town. If you're wanting to do tricks but still make it across town try and get in the low 70's gi. Maybe 46/17. I rode this for a while as well and it was very nice.
