Utilizing a newly developed manufacturing technique never-before seen in the off-road chain
market, ProTaper Pro Series chains feature innovative forged pin collars that have been seamlessly
incorporated into the outer chain plate. By cold-forging pin collars to encase the thermally refined
alloy steel chromium carbide layered pins, outer chain plate thickness can be slimmed to reduce weight
while increasing tensile strength. Featuring Slim O-Ring Technology, which offers superior,
long lasting chain lubrication in a slimmer profile, eliminating the clearance issues of competing
O-ring chain designs. The result is slim, ultra-premium, light weight racing chains with unparalleled
strength and prolonged lubrication over the competition.
