CRUPI Quad Wheels 24"x1-75"

It all starts with the gearing: a chainring paired with a sprocket sets your gear development. A 44/16 setup is a versatile standard; you then adjust it to suit the track and the rider's power.

The 20" is the racing standard from Mini to Pro; the 24" is reserved for the Cruiser. The youngest riders use smaller formats matched to the frame size.

7075 aluminium is light and favoured in competition, while chromoly is tougher for young riders or intensive training. In BMX Race you want the best weight-to-stiffness ratio.
