Product Information

Mobius X8 Knee Brace Set

A relatively new company in the minds of the general public, Mobius and the X8 have actually been worn and tested by Ryan Villopoto since late 2012. Slipped on rather than strapped on, the innovative X8 is held in place by a continuous cable and backing plate system that wraps around the leg and provides natural but firm support. Tightened and released by a front dial, the system is extremely easy to put on and adjust throughout the day. Its overlapping joint provides no gap in coverage ensuring roost and the handlebar won’t make contact with your knee. The PIM glass filled nylon construction is very light (a little over 1lb each) and the sleek design makes gripping the bike very easy and comfortable. For the serious rider concerned about knee protection, the Mobius X8 knee brace should definitely be at the top of your list of ones to consider.


The CCRS (Continuous Cable Routing System) externally reinforces all of the cruciate ligaments. The continuous cable loop is twisted 180 degrees, or a half turn, to form two interconnecting loops. The CCRS cable is routed around the knee joint and when forces are applied to the knee joint, the CCRS becomes tight and resists the excessive movement that can cause injury to the ligaments.

As the Continuous Cable Routing System tightens, it squeezes the brace shells gripping the tibia and femur. The tibial shell is designed to grip the tibial tuberosity controlling the lower leg, while simultaneously the femoral shell and tendon back plate grip the femur. The CCRS cable is routed in such a way that when the leg is fully extended the continuous cable progressively tightens resisting hyper extension, bending, and rotation. When the leg is in flexion, the CCRS cable is designed to progressively tighten as well, preventing rotation and bending.
  • CCRS (Continuous Cable Routing System) adjusts the fit with a single turn of the locking CNC forged 6061-T6 anodized aluminum dial
  • Plush molded EVA foam and impact absorbing rubber internal padding
  • Overlapping patella area with zero degree CNC forged 6061-T6 anodized aluminum stop leaves no gap exposed regardless of how far the knee is bent
  • Figure-8 cable and behind-the-knee adjustment pad greatly strengthen the joint yet work as freely as your body's own ligament system
  • CNC forged 6061-T6 anodized aluminum hinge plates
  • Lightweight PIM glass-filled nylon shell conforms to your legs shape, creating 360-degree protection that will not rotate or slip
  • Velcro® brand closure straps with TPR pull tabs numbered in order to provide proper fitment and easy entry and exit
  • Replaceable foam kit allows you to tailor the fit to each leg

What Other Riders Are Saying...





Cost Benefit

pretty good but...

The good: fits well and the fit chart is accurate. Also, it's not as hot as it looks. The bad:not really. The ugly: It pinch the inner layer of my riding pants at the front where the plastic meets. That prevents my legs from straighten up when I tried to stand on peg from sitting. However, I had to slow down and bend and straighten my leg form once to a few times to get the pinch off.
