The Evolution was developed as part of a research project by
Rohema and the Institute for Musical Instrument Making (IfM).
The 5A Evolution has a significantly longer shoulder than the
classic 5A Stick. This means that it not only generates much more
rebound, but also more speed and drive. IfM's acoustic
measurements also showed significantly higher rebound rates
compared to the conventional 5A Hickory drumstick. The center of
gravity of the 5A Evolution remains absolutely the same, because
the end of the stick was rounded. The weight also remains as
usual, as the Evolution is made from hickory of a heavier weight
class. The higher density of the wood also has a positive effect
on the durability of the stick.
