The ball bearing at the rear sounds a great idea. It would be nice to compare the dynamic ratings of 1920's ball and roller bearings as fitted originaly to similar of today. Bearing improvements in desiign and materials must be considerable. There will be thrust at the front from the single helical timing gears but I don't khow how that compares to magnified foot pressure on the clutch
