Sizing & Fit
Quick answers about the C180™ Rocket before you order. Still unsure? Contact us.
Who is the C180™ Rocket for?
Össur recommends the C180™ Rocket for pediatric (kids') use and for low- to medium-contact and impact activities. It has a condensed frame and Accutrac® hinges modified for young knees. Össur doesn't publish an age range, so choose the size by your rider's knee measurements, not by age.
How do I measure and choose a size?
Take two measurements with your rider standing, weight on the leg: knee width (caliper, side to side at the knee joint) and circumference (around the leg just below the bottom of the kneecap). Sizes are Small: 3"–3.5" width, 9.5"–11" circumference; Large: 3.3"–3.75", 10"–12"; X-Large: 3.5"–4", 11"–12.5". There is no Medium. The ranges overlap, so if your rider falls between sizes, contact us before ordering. Full steps are in the C180™ Rocket Size Guide.
Left or right, single brace or Pair Bundle?
Each C180™ Rocket brace is made for one knee. Choose Left or Right on the C180™ Rocket Knee Brace. For both knees, the C180™ Rocket Pair Bundle – Motocross Edition includes 1 Left + 1 Right brace in the same size plus 2 Motocross Kits. Need a different size for each knee? Contact us before ordering.
How is the fit adjusted?
The brace ships with 6 mm (1/4") condyle pads. Per the Össur instructions, they can be replaced with thinner 3 mm (1/8") or 1.5 mm (1/16") pads, or a shim can be added behind the 6 mm pad for a snugger fit at the knee. All straps adjust in length, the tibial strap also adjusts hinge depth, and the frame is heat-moldable. Follow the Instructions for Use included with the brace.
Riding, Kits & Care
What does the Motocross Kit add, and which kit size do I need?
The C180™ Rocket Motocross Kit includes 1 knee brace undersleeve, 1 set of gear guards and 1 patella cup. It does not include a brace. The Small/Large kit fits Small and Large braces, and the X-Large kit fits X-Large braces. Buying a single brace? Add one kit per brace.
Which extension stops come with the brace?
The brace ships with a 0° extension stop installed, plus 5–10°, 10–20°, 20–30° and 30–40° stops. Per the Össur instructions, always use the same stop on both hinges.
Can my rider wear it with riding gear?
The Motocross Kit's undersleeve and gear guards are made for use with the brace. Whether it fits under riding pants depends on the pants, boots and brace size. If you're unsure, contact us with details of your rider's gear before you order.
Can it get wet, and how do I clean it?
Össur lists the materials as non-corrosive and ideal for water sports. Hand-wash the soft goods with mild detergent, rinse well and air-dry; removing them from the frame first cleans them more thoroughly. Don't machine-wash, tumble-dry, iron, bleach or use fabric softener. After salt or chlorinated water, rinse with fresh water and air-dry. Clean dirt or grass from the hinges with fresh water.
