Hi,
The tribological properties ( ie. low friction coefficient, high wear-restant & Aluminum-compatible etc ) are very important for Dr.Pulley’s sliding roller weight.
We do want to protect our intelligent property but we’re more concerned about all users’s right to choose the genuine parts to avoid any harm from FAKE sliders’s poor quality.
See explanations below and the video series of

The material used for Dr.Pulley’s slider SR1814 is a proprietary self-lubricated composites ( SL-9T series ), it’s Aluminum compatible so the Aluminum-made variator will almost not be worn by Dr.Pulley’s SR. Moreover the friction coefficient of SL-9T series is extremely low so the friction heat buildup is very low. (Dr.Pulley SR’s friction heat buildup will be only 38℃ after 128,000 cycles of reciprocation test )
But the material used in FAKE slider is very abrasive that means the Aluminum-made
variator will be worn very seriously by the fake slider and the friction coefficient of FAKE slider’s material is extremely high so the friction heat buildup is very quick and high.( Fake slider’s friction heat buildup will be quick and high such as 53℃ after 43,000 cycles of reciprocation test for RPM’s fake slider or 53℃ already after 11,000 cycles of reciprocation test for KOSO’s fake slider )
