The new RX-1600-A120 durometer features a scale specifically designed for testing the hardness of skateboard wheels that measures up to 120 on the "A" scale. Normal type A durometers only read to 100 however as wheel manufacturers began to satisfy the demand from riders who wanted harder wheels, wheels with hardness ratings over 100 A became available.
Our RX-1600-A120 features a dial that reads from 20 to 120 on the "A" scale to allow wheel manufacturers and riders to accurately measure their wheels in the over 100 range.
