Hi guys

Does anybody know what the correct offset measurement is for a 1972 Triumph front and rear Conical hub please, there seems to be no reference in the Triumph manual, and I'm not sure I trust what they are at the moment.

Many thanks in advance

This is a modified TSB I received from VMCC a while back. I can't verify the handwritten conical measurements at the bottom, but obviously someone believes it to be true?

Many thanks guys, I can't understand why this info isn't in the Triumph manual.

Like any motorcycle, the front is laced to position the rim in the center of the forks. The rear usually is laced to align with the front.
