Explore the innovative KR concept in rod construction. Improve your assemblies with this advanced and effective method.
After revolutionizing the world of fishing in 1995 with the New Guide Concept (NGC), the famous Japanese brand Fuji presented its new ring concept in 2012: the KR Concept.
The NGC was based on a thorough and optimal study of the number of rings, their shape, size and placement. One of the new points was also to increase the number and reduce the size of the rings on the tip. The benefits of this concept were increased casting distance and accuracy, and better use of the blank's power. The KR Concept takes these advances one step further.
Fuji's engineers have worked on improving 8 axes: more sensitivity, more power, more precision, better balance, better casting, less twisting and less tangling!
The system is simple and can be broken down into two parts: the first rings close to the butt which channel the line and form the reducer cone, and the second rings which lead the line along the tip to form the tunnel. Each of these two assemblies brings its own improvements.
The reduction cone, made up of the new KL series rings, are higher on the leg and also smaller and therefore lighter. This has the advantage of better channelling the line leaving the reel away from the blank, thus reducing friction losses. This channelling of the line is much faster than with the NGC: we speak of forced reduction (the angle of the reel axis is forced, as proposed by the oldest American method of the 27X) achieved with 3 or even 4 rings. This forced channelling quickly eliminates line overrun and brings the line into line with the blank, once again limiting distance loss through friction. Finally, the shape of these rings, already present on the K series, avoids the majority of knots when casting.
The other rings of the ramp forming the tunnel are smaller, lighter and more numerous. Although there are more of them, their considerable weight reduction facilitates the transmission of vibrations, making the rod more sensitive. The increased number of rings enables the line to better follow the actual curvature of the blank, which in turn makes better use of its power and is more efficient when striking. Finally, as the inter-ring spacing is reduced, the line once again reduces friction losses and therefore increases casting distances.

As you can see, mounting your rod in KR Concept has nothing but advantages!
