I'm not saying that u cant use 50x15 in the street... sure u can, why not? but a lighter gear like 48x16 or 17 is more productive in the long term as a rider, style, performance will improve... cadence.. etc etc... I've seen a girl here in DC that rides a nagasawa I think, she works in DC, her style and pedaling technique are super pure... i went bananas watching her pedaling... using heavy gears u dont get that at all, by the opposite, it makes the situation worse... Well im talking to much s...t!... have fun
