Additional Notes
1st Rumblefish frame built. Had to over come chain line issues and resign the rear end for production.
Frame was built with True Temper chrome and Columbus Nivacrom (40% stronger then 4130).
All tubing was manufactured in the shape that’s on the frame, it’s not round tubing smashed into an oval.
In the mid 80’s I could buy a GT Pro Series frame and fork from GT for $35.00. The main tube on the
Rumblefish cost me $35.00 from True Temper. Just a single tube was $35.00. Not all chromoly is created equal.
Standard 4130 is relatively cheap. Tubing from company’s like True Temper (sadly out of business) and Columbus
are much lighter and stronger but cost much more.
Geometry was taken from a Rebel General Lee. I really like the way this bike rode. It came out of the gate quick and fast.
It turned very good and was stable in the air. A well rounded bike. Short rear end and long front.
I design all my bike to be race oriented first, I grow up riding and racing Bmx and motocross. I always loved the factory
built motocross works bike of the day. This was the idea of Rumblefish, a works Bmx race bike for pro riders.
Thanks for looking.
