The ER-1 compound was developed by Hawk Performance for the endurance racing market with the goal of providing a higher coefficient of friction than competing endurance pads while maintaining equal or improved lifespan. Extensive testing at major races across America has resulted in a compound that delivers ideal modulation and pedal feedback, with exceptional friction stability throughout the thermal range.

This consistent performance over long periods makes the ER-1 suitable for endurance racing, track days, time trials, and sprint racing.
