Your bike is only gonna go as far as your wheels take you, so cop a better set of rims. Velocity's Deep V rims are double walled and super thick for durability, and come in an array of colors and patterns for customization. Alternately, the Vuelta Zerolite Track Pro wheels are solid, have a good repuation, and often machined for compatibility with brakes.
