Way back in the stone age when BMX was young. A great deal of innovation was being done in order to get that extra edge. This was not limited to the So-Cal scene. The more I look into it, the more I realize how the whole scene was moving in different parts of the country in parallel, or just weeks behind. This is specially true of the NOR-Cal scene.
A while back the OM and I had a good talk about how BMX spread like wildfire. He mentioned going up to Nor-Cal and battling it out with The Silver Shield BMX team which included people like Friendly Fred, John Wells among others. He also mentioned a certain Pete Harrigan and his bikes. Thanks to Mike "Spike" Rush (another Nor-Cal 70s icon,) I managed to get one of Pete's innovative frames.
The frame is a modified Schwinn Sting Ray. Main reason was in order to run longer cranks.
This picture shows where the bike was cut and rewelded along with a cool chainstay reinforcement
