1997 Dirt Master Big Bertha

Sold to Nick (cyclepsych0) Enjoy it brother! Prototype Big Bertha Frame No Serial Number Original owner said he got it in 1994/5, but he said I should check with PK for the exact date.

I picked this one up from the guy who got it to test.


This is what he told me:

This frame was given to me to test by Perry Kramer and Mike Devitt. 22" toptube full cromo welded by Sal at S.E. Racing California. 

He said the head tube ovalized in the first year and was replaced by S.E.

It was originally black, but was done in white when redone.

I'll try to find out more and update when I do.
