Dagger models are equipped for strenuous use with additional protection from a two-component hard shell at the knee. The patented Squeezebox system allows the protector to move when pedaling and supports a high degree of comfort of the Dagger. These protectors that were developed with Darren Berrecloth, also provide some protection for the shin and the upper leg. The iXS protector meets European safety standard EN1621-1 resp. EN1621-2.
