KR Groups

KR Concept Update:
Unmatched Performance in 4 easy steps!

Fuji’s introduction of the KR CONCEPT was met with great enthusiasm and some trepidation as rod builders across the world tried to get a leg up on new ideas such as ”Rapid Choke” and ”High Frame Small Ring” Strippers. In addition, they were asked to decode a completely new set of high frame KL guides that looked ”brand ” new to most custom builders .

Clearly, the ”concept” needs simplification and Fuji has seen the light. In fact, with the following information, you should be able to build an excellent KR CONCEPT rod on your first attempt!

 

Understanding KR Concept "Groups"

Adding 7 new guide heights to the KL-H Selection in 2014 completed an effort by Fuji to allow entire reduction trains to be custom fitted to various rod characteristics. The sizes and heights have been carefully engineered to allow the guides to form ”groups” that will automatically space themselves along the blank at the right interval and right height for certain reels, lines and actions. Carefully choosing a ”group” is simple and makes the balance of the build very manageable.

As you can see from the photo, a ”group” will always space itself properly along the blank REGARDLESS OF THE LENGTH OF THE OVERALL REDUCTION TRAIN. Only when ”groups” are broken  does spacing and height become an issue. If you choose a ”group” based on what you intend to use the rod for, you’re 75% of the way to an exceptional KR CONCEPT rod.

Carefully consider the final purpose of the rod you intend to design with reel size, line choices and rod action in mind. Choose the group below that best fits your intentions.

STEP 1

Select from the above groups based on the action of the blank and what you intend to do with the finished rod. These groups will provide a well spaced reduction train on a wide variety of finished  rods.

STEP 2

Locate the stripper guide on the blank according to NGC instructions using the Table Edge Technique or GPS Software.
Note: if the reel is completely unknown and NGC is out of the question, Fuji’s research will position the stripper between 20 and 30 inches in most cases for rods 6’6” to 8’ in length. These suggestions are designed to work with ANY reel and are generally good enough for the primary set-up of any rod. Extrapolate, tape and test. Table edge and GPS will usually place the stripper a few inches closer to the reel. Note: In our own research we have found that for rods from 6’9″ to around 7’6″ a stripper position near 19-inches seems to provide the best performance with 2000 to 3000 Series reels. Our go to stripper position for a 7ft Medium action rod is 19.5 inches – a little less (18.5 inches) for shorter rods and a little more (21 – 23 inches) for longer rods.

STEP 3

Measure the distance between the stripper position and the tip of the blank and multiply that number by .45. Place the choke guide this distance beyond the stripper.
Example: 42 inches from stripper to tip of blank
42 X .45 = 18.9
Place the choke point 18.9 inches from the stripper.

STEP 4

Position the other reduction guides on a line between the stripper and the choke guide to form a bulls eye when viewed through the stripper down to the choke guide. Note: For an additional performance tweak, from the bullseye position, move the bottom of the choke guide ring to the top edge of the last reduction guide. We have found that this can “help” the line make the directional change required at the end of the reduction train.

Choke relative to reduction for kr

Fuji suggests static loading to determine the position of remaining running guides. Use one more guide total than the length of the rod in feet. Example: For a 7 ft blank, use 8 guides plus a top guide.
