I am honored to work with my good friend Ricardo from Oak Wheels in Portugal on these amazing collaboration wheels! Oak is probably the oldest Urethane fingerboard wheel brand that is still in existence to this day, and they're known for their slogan "mucho feeling" for good reason; Oaks are some of the most amazing feeling wheels out there! Combining with the FlatFace inner cores and the Oak material on the outside, you get the best of both worlds, with a unique shape and great performance. If you like Urethane wheels, these are the one's for you!
