"SUPER CERAMIC"
Made-in-Japan, highest grade, high precision ceramic balls are used to ensure super smooth and long-lasting rotation. Cyclists need to adjust power and cadence depending on terrains, so the ceramic bearing is most effective as less energy is required to turn the crank. It offers remarkable performance gain under high load conditions such as competitions.
As SG75 Series use a proprietary taper called "SG75 taper", SG75 crank should only be used on SG75 bottom bracket.
