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.

Great Chew Toy
We have a Boerboel, and she destroys all toys. And I do really mean ALL toys. But Benebones hold up great! They're truly impossible to actually break. They will eventually get flaky the more they chew on them, and once they get super flaky, you'll need to replace them. But I'd say with our super chewer, who chews on them multiple times a day, we only have to replace Benebone products about once a month. These are a must have if you have a super chewer.

Benebone... Best dog toy!!!!!
This is my dog's fave toy hands down. The Benebone brand is the only brand of bone I buy. My dog weighs 85 pounds and can really chew on a toy and these bones hold up well. They are the best in my opinion. They have several different flavors. He likes the bacon and PB. I love how Amazon has the "buy again" option. It just makes it so easy to repurchase your items. I usually buy the "Y" shape b/c it's easy for him to hold between his paws. BUT.... Sometimes I will buy the 4 pack if I need a good deal.

No more dental cleanings!!!
I have a 68lb Pitt mix who has consistently chewed on her bone since it was delivered over 4 years ago and she has just barely chewed the nubs down. This bone is indestructible and will keep your dog’s teeth clean. Daisy is 9 years old and does not have any tartar build up and has never had a dental cleaning. She just had her check up and vet said her teeth and gums look great!! Highly recommend this for your dog!
