Important Notice regarding color
7/14/2021 - we were informed by IST that the KNEE lever has undergone cosmetic changes to address a performance inconsistency with the red plastic. Our unbox photo shows the older color. The new colors are black case with red metal plate. Additionally, the aluminum actuator is no longer used, replaced by a nylon/urethane actuator. This was to address control issues reported with the original actuator.
ROX Dragons | Jaemin "Knee" Bae's legacy as the undisputed all-time best pro Tekken player in the world has begun to spread to the western continents. In 2019 alone, KNEE has won or placed high in no less than ten (10) Tekken specific events, including EVO Tekken, Tekken 7 World Tour at Combo Breaker, World Showdown of ESports, and Japan Mastercup 11 Championship.
These achievements were done in part by his own custom lever, which features a number of components designed with his and other pro Tekken players feedback such as Chanel. The IST KNEE lever wraps these unique characteristics into an attractive package inside and out.
Compatible with Sanwa Mount
The KNEE lever does not possess a 35mm collar and its multi-mounting plate possesses holes to install in Sanwa-compatible fightsticks that have enough clearance.
Notes For New K-Stick Players
If you are coming from a Sanwa JLF or other Japanese style lever, some worthwhile notes to keep in mind
Round Type - No Gates
Korean sticks do not possess any restrictor gate. Instead it moves freely in a circular fashion. There are no restrictor gates that are compatible with this lever.
Tension via Rubber Grommet, Not Netal Spring
Additionally, there is no tension spring. Instead most Korean levers use a rubber grommet placed in the housing. This surrounds the shaft, and a plastic or delrin bobbin keeps shaft in place.
Available separately, IST rubber grommet are uniquely color-coded to represent their hardness/tensile strength, making it easy to identify if you desire to switch to a different tension. Each are made of silicone rubber, with the exception being Shore A 45 Black, which is manufactured from natural rubber. The list below details each color and hardness.
|Shore A 25 White
||Shore A 30 Yellow
||Shore A 32 Violet
||Shore A 35 Blue
||Shore A 40 Red
||Shore A 45 Black (Natural Rubber)
Straight Hinge Microswitch, .187" Terminal
Microswitches without a straight hinge are incompatible. If you are planning to experiment with microswitches on your new K-Stick, be sure to purchase straight hinge type.
Tested Compatibility with Fightsticks
The KNEE lever dimensions are 95x83x118mm. (3.74 inches long, 3.26 inches deep and 4.64 inches high) with shaft installed. Without shaft and including the microswitches, the base is 38mm high. IST confirms the following FightSticks are compatible with the KNEE lever. Its fit is similar to the Crown 303-FK. We will add to this list as we perform fit tests with other models in our possession.
- Hori Real Arcade Pro V Hayabusa (includes RAP 4 Kai, RAP 3-SA/SX as it uses similar housing)
- Hori RAP N
- Hori Edge (original and 2017 model)
- Hori VLX (all models)
- Razer Panthera (not Panthera EVO)
- MadCatz TE2+ (also compatible with original MCZ TE2 models)
- Qanba Q1 CUT
- Qanba Obsidian
- Nacon Daija
- Joytron EX Revolution V2
Included with Purchase
The KNEE lever comes with several parts such as laser engraved clear battop, aluminum actuator, anodized aluminum shaft, wrench for attaching and detaching the shaft, dustwasher, aluminum actuator, and 3 e-clips (helpful as e-clips are easy to lose), all packaged in a stylish black box. You will also find paper instructions for installing the shaft, battop, dustwasher, and actuator with e-clip.
Parts for Performance
Some of the unique characteristics of the KNEE lever fall into its custom grommet and actuator along with non-Korean standard decisions for switch and shaft. These were based on feedback from KNEE himself, along with players such as Chanel, and now serve as KNEE's daily driver:
Omron V-152-3A5 Microswitch
Omron is a well-respected microswitch manufacturer. The KNEE lever takes a departure from the common Gersung brand to instead utilize these long-hinge microswitches that promise a lifespan of 50 million clicks and high sensitivity.
35 Shore A Hyper Tension Rubber Grommet
Seemingly unique to the KNEE lever is the white 35 Shore A grommet - a softer tension that appears it possesses a faster return to neutral. There may be a higher tension towards the center of the grommet hole, which the bobbin attaches itself to.
15.5mm Aluminum Actuator
The red anodized aluminum actuator is both style and substance. IST reports that the actuator's diagonal zone is weighted towards the bottom to provide a faster down to diagonal input.
Anodized Aluminum Shaft
Another departure from the standard design of most Korean levers is the anodized aluminum shaft. This lighter-weight, corrosion resistant shaft also contains a Sanwa compatible threading, allowing you to install a wide variety of aftermarket balltops and battops if you so choose.
The body casing is made of urethane, which has a higher tensile strength, a good resistance to abrasion compared to plastics.
