S67A big 6 piston caliper

SAVANINI's S67A brake caliper is the caliper with the largest piston area currently in mass production.It adopts aluminum alloy forging technology and has high rigidity, high tensile strength, high toughness and high density. Compared with cast aluminum alloy calipers, the rigidity of the SAVANINI’s caliper has increased by about 50%, which effectively reduces the risk of caliper breakage during application. Compared with ordinary external dust covers, the built-in double oil seal design makes the brake feel and reaction speed more sensitive. It has excellent braking performance. After anodizing, vacuum coating CVD color fixation effectively solves common problems such as paint cracking and paint shedding, giving it a metallic texture and brilliant color. After installation, the entire wheel hub looks more attractive, perfectly coping with various road conditions, whether it is daily travel or sightseeing, it can also go on the track.
