Graphite shaft question?

Question

Had a question on graphite shafts?What is the differance when you see like,3.5,4.5,6.0,on the shaft?I know what the flexes mean,just not these numbers.?

Answer 1

It's the torque number, the resistance of the clubhead to twist during the swing and it's measured in degrees.  3*-4* is the usual numbers on shafts today.   Older shafts with numbers less than 4 felt boardy, but with technology today that is gone and there are shafts with torque numbers under 2*.  Rifle numbers their shafts 4.5, 5.0, 5.5, 6.0 for flex but they only make steel shafts.

Answer 2

The torque number. the lower the stronger tip.

Answer 3

It could be either:

1) Torque rating (how resistant to twisting of the shaft)

2) If you are looking at Rifle branded shafts, they use numerical ratings instead of alpha rates (A, L, R, S , etcc)
