Shaft Stiffness

The Ultra Light and Ultra Light Nano BRAČA-SPORT® shafts are available in many precise levels as shown in table below. Each shaft is designed and built for a specific stiffness and then measured and verified for accuracy before it is assembled. The stiffness variable (deflection) of the oar is measured using a 10kg weight as shown in the figure above. For any set of sculls or oars, the stiffness will vary no more than ± 0.1 cm.
