Allenite Cam Cleat Medium. Allenite Plain Bearing Cam Cleats feature the same jaw profile as the aluminium version, but the jaws and base are moulded from a proprietary material developed specifically for low weight and good heat dissipation to increase wear resistance when compared to standard acetals. The removal of ball bearings offers a further weight reduction. The Allenite cam cleat offers a good weight saving over the aluminium version.Allenite cam cleats are designed as a cheaper alternative for low load applications.
