The MKS BM-7 pedal has a serrated, saw-tooth profile on the rim of the pedal cage which provides grip to any type of footwear. The chromoly axle is mounted to an alloy body. The anodized aluminum alloy cage is then riveted to this alloy body. High quality loose-ball  bearings are used for smooth action. It's constructed in the Mikashima Industrial Company (MKS) factory in Japan, on the same machining tools and equipment for the past 40 years.
