More common chassis used is a 900mm, newer chassis have wheelbase adjusters that will allow you to change the wheel base out to 940mm.The chassis should be manufactured from 28mm tube which suits lighter weight karts and drivers. The Cadets use a 30mm hollow rear axle that is designed for use with drivers in the 6-12 age group.
