A properly installed set of composite kneecups in your C1 will get you felling 'at one' with your boat in no time. Kneecups can be held in place with shaped foam, but installation using epoxy resin and a compatible composite cloth is recommended for best performance. Since everyone's knees are knobbly in different places, we suggest that you try before you buy! Available in 2 sizes - skinny and standard.
