Most shaft companies produce several lines of shafts using the same mandrel.  The mandrel is the metal core around which the sheets of carbon fiber are wrapped and baked.  Each shaft line's playing characteristics are determined by sanding the tip and butt of the shaft differently for each.
 
In other words, one base shaft is used to model different shaft lines for a manufacturer.

The guys at SMT looked at these finished/sanded shafts under a microscope and noticed something very interesting.........many of the graphite fibers were compromised or destroyed from the sanding procedures.

That means the shaft can't transfer 100% of it's energy to the clubhead.


A Different Kind Of Feel.

RLM stands for "Reactive Linear Motion".  These shafts are filiment wound, which means they have virtually no spine and are much more consistent than shafts made from sheets of graphite material.

RLM shafts rely upon the mandrel that's used to wind the fibers to give each shaft it's playing characteristics.  The sanding procedure - which destroys the graphite fibers - is virtually eliminated.

In fact, nearly 95% of the fibers in an RLM shaft are still intact after sanding compared to about 35% for other shafts!  Less sanding means less fiber destruction for the shaft.

That means you get a shaft that simply feels better.  There's more life in the shaft because there's more graphite fiber left intact.  The graphite fibers are necessary to transfer the shafts energy.  Less fiber -- less energy.

The bottom line?  These shafts look good and perform even better.  In fact, the RLM lineup is the only shaft I use when I build any SMT driver for my customers.
