They are both modern components engineered for durability after extended use. Included also is a forged alloy crank with an 46T alloy chainring and an 18T cog and freewheel. Note the stylish wheelset, which hosts deep section rims and sealed bearing high-flange flip-flop hubs. Suffice it to say, the unit is especially built for urban and well-populated environments. Overall, the Schwinn 2010 Madison is recommended for users seeking durability and flashy style in an affordable package.
