[1] After obtaining his engineer's degree in Design Engineering from Delft University of Technology in the Netherlands, Hol became involved in a graduate project with Interraps - a Dutch producer of inline and ice skates - working on a planned improvement of the first (Viking) clapskate design with the aim of turning a 100-year-old patent into a product that could break ice speed skating world records.
With previous employer Interraps possessing the patent that basically covered all existing inline frames at the time, Hol was driven to come up with something completely new.
This shift was partly motivated by the popularity of the Omega aero-helmet among triathletes in the Dutch national competition.
Two Dutch Technical Universities have tested the most recent helmet in various conditions, from long-track sprinting to marathon and team pursuit.
[5] For improved safety, Diederik invented the honeycomb structure, which absorbs shocks better than traditional EPS foam and makes it impossible for sharp skateblades to penetrate through the ventilation holes to the head.
