Product Description


Mobius X8 Knee Brace

  • Innovative, patent-pending design is the pinnacle of knee brace technology, form and function in sports protection
  • Mobius innovative Continuous Cable Routing System (CCRS) externally reinforces all crucial ligaments of the knee for maximum protection
  • Cable routes around the knee joint through the tendon back plate. When extreme force is applied to the knee joint, the cable progressively tightens to provide support and prevent excessive rotation and bending
  • CCRS also grips and squeezes the brace shells gripping the tibia and femur to provide additional support to help prevent any additional excessive movement of the knee joint
  • Brace outer chassis fabricated with lightweight PIM glass-filled nylon that conforms to the shape of the leg to provide natural freedom of movement without binding
  • Knee brace design also prevents the brace from rotating or slipping out of position
  • CCRS system features a locking, CNC-forged 6061-T6 aluminum dial for adjusting cable tension to a custom fit
  • Plush molded EVA foam and impact-absorbing rubber internal liner aid in fit for maximum knee protection
  • Durable CNC-forged 6061-T6 aluminum hinge plates
  • Overlapping patella area with CNC-forged 6061-T6 aluminum stops leaves no gap exposed, regardless of how far the knee is bent
  • Hook-and-loop attachment straps with numbered pull tabs provide a proper custom fit and easy on/off of the brace
  • Braces are sold in a left/right pair

    I've tried out a lot of different braces but, these are by far the best braces I have ever rode with. Easy to put on, adjust and very durable.

    Just recently bought these braces and after three rides on them they are comfortable and supportive and work well. Had issue with fit on the first pair and exchanged for medium without issue. If you are not on the upper end of the measurement range best to size down. A bit of a pain having to slide them up your leg to get them on because you have to remove your pants so just wait to get dressed until at the riding area. Need to get some under-sleeves. A little tight on some of my riding pants and unusable on two pair. I'm considering trying Asterisk Cell braces because they are velcro strap system and might be better fit. Mobius are a little tight on either side of knee when putting them on but doesn't seem to be an issue when riding and I don't notice it at all.

    Questions & Answers

    • should my measurement be with my knee bent or straight

      By: Guest

      The best way to measure a Mobius knee brace is with a straight leg. You'll want to measure the circumference of your leg about six inches up from the middle of the knee cap. In the instance you find yourself on the borderline, go a size up. We've found that Mobius X8 brace sizing can run slightly small as the knee diameter doesn't exactly correspond the X8 brace measurement at the thigh.
