• I ran 48x16 for about 4 months, going from 16t to 18t makes a difference, more control at lower speeds, spinnier, yet more fun, and not so hard on the knees. you'll enjoy riding fixed a whole load more when you swap over.
    I rode 48x16 during the summer and its fine, still a bitch to get moving , but when your on the go its cool, in winter or when it gets gusty, not so cool, the added resistance from the inclement weather is main reason for me changing to 18t.
    also I think when you figure out your gearing moving from a geared bike to a ss or fixed, you should always choose a gearing lower than that to allow for the added exertion of pedalling all the time as well as braking
