Fabricated of a hybrid carbon/glass weave and machined out of Ronix's new Dark core blank - up to 20% lighter than their other secret squirrel concoction. The dark core has a 3 month cooking time before all of the properties have totally cured and machined into a blank. This type of material is now common in big ships because it always wants to recoil to its original structure. This added energy means a board will want to maintain its rocker line thru a transition, trough of the wake, and impacts on landings more so than a traditional construction. A stiffer, lighter, alternative. demanding core setting the standards for riders looking for the most refined creation available. Ronix's team has spent the past couple years tweaking the flex, while our engineers made sure it was stronger than any other construction. More than just another core - Ronix's team swears by it.
