The Skyway Tuff Wheel II Mag 16" Wheelset is the same as everyone's favorite 20" version just scaled down for the smaller shredders. For the most part these mags are just like there were in the 1980's but with a better sealed bearing hub. These are perfect to finish off your retro build, fix up that old BMX bike or to just look cool. These wheels are a pair (front and rear) and have 3/8" (10mm axles) and work with most 16t or larger freewheels. The freewheel is not included.
