The Marek Bio features one of the most advanced constructions available. Its bio core has a reduced volume for lightest overall feel. Edge response and good speed into the wake have always been keys to the Marek's performance, and the four 9° angled fins helps create an incredibly responsive feel. Abrupt continuous rockerline allows the Marek Bio to consistently provide solid pop. Marek Bio 145: 57.1"L x 17.4"W. For riders over 170 lbs.
