How can you say someone elses sprocket is too big? It depends totally on how strong their legs are and how fast they ride on average? Maybe he's running a 50t because he's a tank and he uses his bike only for racing his dad's car down the road. Or maybe he uses it for mad trials moves and wants some tiny motherf*cker. Or maybe his dog's best friends monkey...... whatever. His choice. f*ggot.
