Just christ 48/15 is pretty much unskiddable, even if you are balls on stemming it. I know some huge bros will come in and say "ANYTHING IS SKIDDABLE" but Im a skinny guy and I had to balls on stem it to skid 77 gear inches, I cant imagine locking up 84.2 gear inches. If any of your friends ride fixed try their bikes. After riding a friends bike who was riding 65 gear inches, I switched from 77 to closer to that.
But to sum up the thread that is about to ensue "dont skid tires cost more than brakes go buy a ****ing brake hipster dont skid skidding is gay buy a brake search the forum"
