The Quantum Bearing Science Ryan Decenzo Signature Pro Series Isotope bearing kit puts Ryan's signature on Quantum's Isotope ceramic hybrid, a bearing designed for the high impact street and park skater who wants the speed of a ceramic bearing with the mechanical durability of an all metal design.

Isotope bearings feature high precision chrome steel inner and outer rings, doped zirconium oxide (ZrO2) rolling elements for frictional, thermal, shock, and impact resistance, diamond polished raceways and rolling elements, a high strength thermoplastic cage, and Quantum's Graphflo engineered lubrication process. Every bearing is burned in at high speeds and tested before it ships.
