Each belt is molded on Rega's highly accurate custom tooling using a unique secret blend. Once molded, the belts are cryogenically frozen and barrelled to remove any excess flash in order to create perfect cross-sectional roundness which is critical for accurate speed and stability. In normal use and conditions, the lifespan of the EBLT drive belt is 50% longer than the previous model. All Reference belts go through a unique curing process that guarantees the highest achievable level of accuracy.
