The cord tapers from 0.50mm eg to 0.30mm at a length of 12m.
The Tapered Leader was developed by Carp'r'us to get the most out of your casts.
The leader is used when casting with braided lines. Due to the club shape of the line , it is possible to throw violently without risking a line break. The tapering at the end of the leader, to which you knot the main line, ensures that the knot is significantly smaller and therefore flies through the rings much more easily.
