Your authoritative resource for BMX, Old school to New

With the success of the standard 20" frames Gary and Craig targeted the smaller riders under 10 to have better handling and lighter bikes in 1977.  


This superior mini chromoly frame is manufactured to the same specifications of quality and strength as the standard frame but has been designed for the junior racer.  The bottom bracket and seat tube are lower to the ground and the wheelbase has been shortened.


The mini chromoly frame is also manufactured with your choice of bottom bracket: Sealed-bearing spindle or standard bottom bracket. 


Cook Bros. frames have been tested on Southern California tracks to allow us to construct the best frame possible and are warrantied for one year from the date of purchase.


WEIGHT - 3lbs. 7oz.

MATERIAL - 4130 Chromoly throughout

WHEEL BASE - 33 1/2"

There was also a matching Mini fork that would only accept 20 x 1.75 tires.  This fork makes the front end lower and therefore steers faster.
