Well 30 mph is around 48 km/h... with 48x14 in the street??? well besides being a lot of gearing for the street if you can do those speeds you should do track racing, well... not really but yes you can do those speeds with 48x14 the issue is for how long? 48x14 is around 51x15 and thats a lot of gear even for people that do track racing. Average per points races RPMs is over 100 so I believe the kid, what i do not believe is the gearing he is using for the street

Probably you are the HOY of the asians or something

Just assuming you are asian maybe you are not.
Well good for you... as for the lady... 56?? well, that I would have love to see

Next time talk to her or something, you might even get laid that day
