The SKS X-Board and X-Blade 29'' Dirtboard Set is a great set of guards if you are enjoying the super wet trails and sloppy cross country riding. The set consists of the X-Blade which is a 2-component dirtboard for the rear wheel of mountain bikes. Due to the quick-release mounting, the X-Blade can be fitted to almost any seat post and optimally adjusted to the wheel using the 2-joint technology. The X-Board is an innovative front guard with rubber straps fitting on the downtube, and the same 2-component construction as the X-Blade to form a matching pair. Supplied with adjustable cable spacers.
