Alpinestars - RK-1 Plasma Knee Brace

Anatomically profiled for all forms of off-road riding, the RK-1 PLASMA Knee Brace has been engineered to provide comfortable knee support while still being lightweight, breathable, and protective. This knee brace features a Nucleon PLASMA knee protector encased in an innovative hybrid frame construction, consisting of a flexible composite over-injected on a high-performance polymer blend to offer superb frame rigidity while still being flexible at the upper and lower strap areas.

  • This brace provides optimal structural integrity and support while being ultra-lightweight and adaptive, and thus reduces the risk of sustaining injuries to the medial and lateral collateral ligament, the anterior and posterior cruciate ligament, and the lateral and medial meniscus.

  • The replaceable triple segmented knee cups are constructed with a polyurethane outer shell backed with a Nucleon PLASMA protector for the optimum blend of impact protection, flexibility, and scratch resistance.

  • The self-centering knee cup and the strategically positioned upper and lower patella extensions ensure maximum coverage regardless of the flexion or extension angles.

  • The extremely stable, slim-design four-point hinge system perfectly follows the articulation of the knee while the extension stops, which are available in a range from 0 to 30 degrees, assist in setting the brace to the desired maximum opening angle.

  • The stainless-steel bushings in the four-point hinge system have an anti-oxidation treatment.

  • Nucleon PLASMA is a viscoelastic material engineered from bio-based polymers and formed into a structure that is pliable in all directions while maintaining the ability to dissipate impact energies. Lightweight and highly ventilated, the knee protector offers strong impact force dispersion and absorption while ensuring maximum coverage in all riding positions.

  • This knee brace features a Nucleon PLASMA knee protector encased in an innovative hybrid frame construction, consisting of a flexible composite over-injected on a high-performance polymer blend to offer superb frame rigidity while still being flexible at the upper and lower strap areas.

  • The replaceable triple segmented knee cups are constructed with a polyurethane outer shell backed with a Nucleon PLASMA protector for the optimum blend of impact protection, flexibility, and scratch resistance.

  • Constructed from USDA certified bio-based eco-friendly and sustainable impact absorbing material.

  • Soft-touch thermoformed padding ensures the highest levels of rider comfort while keeping the knee brace securely in position. Replaceable as a spare part.

  • Soft-touch thermoformed condyle padding comes in different thicknesses for a customized fit. Replaceable as a spare part.

  • Equipped with four individual straps backed with a non-slip material to ensure the knee brace remains securely in position while riding.

  • High tensile strength buckles are robust while still being flexible for easy strapping and adaptivity.

  • Central buckles are easily locked into the closed position by a keyhole snapping system.

  • Inner-knee central buckles are mounted internally inside the frames to avoid contact with the bike.

  • The CE-certified Level 1, RK-1 PLASMA Knee Brace provides optimal structural integrity and support while being ultra-lightweight and adaptive, and thus reduces the rider’s risk of sustaining injuries to the medial and lateral collateral ligament, the anterior and posterior cruciate ligament, and the lateral and medial meniscus.

Not Durable Enough
Color: Colorful, Color: Colorful
These worked SO WELL... For one night. Maybe my pupper is just super destructive with his chewing, but he had a chunk of the top of the pineapple off less than 10 minutes after opening the package. That being said, the concept is perfect. He is very active when I'm trying to settle him down for the night if he hasn't had enough activity during the day. This translated to him trying to chew everything (including my arm, and RIP my comforter...) I wanted to find something for him to chew on that would help sooth his teeth/gums, since the other toys he loves weren't interesting enough to keep him engaged. Unfortunately, despite one night of his chewing relaxation, he chewed right through them. At least I know the concept of a frozen chew toy is the correct intervention. I'm just sad that these were destroyed so quickly!

Lay flat handle is a game change
This dog steak is made of quality steel easy to install and has held up overtime. I would highly recommend. I bought this dog steak over two years ago. Immediately and easily screwed it into the ground for a secure hold. The lay flat handle is convenient for attaching a cable or rope to tie your dog up to. The lay flat handle, makes it easy and convenient for mowing your lawn. I have never once pulled it or moved it in order to mow our grass and after two years, it has remained as secure as it was the day I screwed into the ground.

Don’t waste your money
Color: Colorful
My dog wouldn’t have any thing to do with these. The hole where you fill with water doesn’t close in anyway, so water leaks all over. Wouldn’t purchase again.
