Description
The X8 Knee Brace is the most protective, comfortable brace on the market, utilizing innovative patent pending technology which incorporates the CCRS (Continuous Cable Routing System) to form an unparalleled system of support and protection. The forged CNC machined dial makes fit adjustments on the fly and through pants easy. Fully lined with plush EVA foam, a comfortable, impact-absorbing surrounding is created. Includes one pair of braces and two extra sets of patellar shell pads for a precise fit.
STEP 1
Completely undo Velcro straps #1, #3 and #4.
STEP 2
Pull up on the #2 Tendon Back Plate Cable Release Button above the Cable Tensioning Dial and pull out the #2 Tendon Back Plate as far as it will go. Then slide the X8 over your leg and center the Patellar Shell over your kneecap while bending your leg. The brace should fit snug on the sides of your knee. If it is loose or too snug, choose the appropriate, included Patellar Shell Pad to achieve a snug fit against the sides of your knee.
STEP 3
While holding the Tibial Shell firmly against your upper shin, attach Velcro Strap #1 locating the Tibial Strap Pad above your calf muscle and just below the crease behind your knee.
STEP 4
While holding the Tendon Back Plate against the back of your thigh and above the crease behind your knee turn the Cable Tensioning Dial clockwise until the cable is tight.
After adjusting the Cable Tensioning Dial to your desired amount of resistance, there should be between 0.10” (2 mm) and 1.00” (25 mm) of exposed Cable. If the distance is less than 0.10” (2 mm) or the Cable Tensioning Dial locks out, then try replacing the standard Tendon Back Plate pad with the included thicker Tendon Back Plate pads. If you still can’t achieve the proper tension in the cable, then you need a smaller brace. If the distance is more than 1.00” (25 mm) then you need a larger brace.
STEP 5
Attach Velcro Straps #3 and #4 and re-adjust Cable Tensioning Dial, if necessary, so that the Cable is as tight as you can make it without being too uncomfortable. The tighter you make the Cable the better knee protection you will have.
To remove the brace first remove Velcro Straps #1, #3, and #4. Then, while holding back the Cable Release Button pull the Femoral Shell away from your thigh until the cable is completely extended and remove the brace.
CUSTOMIZING YOUR FIT
Everyone’s legs are different shapes and sizes and many people have different size legs. Mobius X8 Braces are completely customizable to accommodate different leg sizes and shapes.
Your braces come with two different optional thicknesses of Patellar Shell Pads so that you can get the brace to fit as snug as possible against the sides of your knees.
Many people have smaller or larger than normal upper legs and many people have smaller and larger than normal lower legs. To accommodate this Mobius offers Complete Pad Fit Kits for the X8 Braces.
For example: If you fit a Small or Medium brace, but your lower leg is relatively larger, then you could replace the Tibial Shell Pads with thinner pads from a Medium or Large Pad Fit Kit. And you could replace the lower Straps with larger Straps from a Medium or Large Strap Kit. The same can be done for the upper leg.
Your braces come with optional degrees of extension stops to limit full extension if desired. The extension stop installed on the brace is at 0 degrees, and included are 4, 8 and 12 degree stops.
SIZING GUIDE
Measure from the center point of the kneecap to 6 inches up the thigh. Measure the circumference of your thigh at that point. With this measurement, follow the size chart below.
WARNING:
• If you fall between two sizes, choose the smaller size.
• If the #2 Tendon Back Plate contacts the shells and will not tighten any further, the brace is too large for you. Using an X8 that is too large for you will not function as designed and will not protect you properly. It may also cause premature wear of the device and may void the warranty.
