1923 sports rear axle

[Ian Williams]

I would like to see you achieve an average speed of 76.84 MPH for 3 hours with 26" BE rims with a 4.09 axle Marcus thats all I can say, bearing in mind also that this is an average speed not a maximum. Agreed that is was an impressive performance but lets not forget he was fully works backed and I don't believe responsible for the mechanical other than final set up in the cars he raced, I believe he had ideas and suggestions, but with full factory mechanical development. A brand new i 1/8" crank at constant speed may well survive three hours close to 5000 rpm. I have personal experience of a 1 5/16" surviving many many hours at those speeds, I would sit on the motorway a good hour and a half each way to and from Beaulieu year after year at those RPM as well as many road miles sprints and several races before it finally let go after approaching 10'000 miles of abuse. This was a crank of unknown parentage so I can fully believe a new 1 1/8" would survive a fraction of this.
