Description
ProTaper rebuilt the 520 racing chain from the pin outward with the Pro Series line, and the forged master link is where that engineering shows up most clearly. Instead of a standard riveted or clipped connector, the pin collars are cold-forged directly into the outer plate, the same process used on the rest of the Pro Series chain. That means the master link is not a compromise part bolted onto a premium chain; it shares the same construction as every other link in the loop. Chromium carbide layered pins resist wear at the point of highest friction, while the forged collar lets ProTaper trim plate thickness without giving up tensile strength, so total chain weight drops while durability goes up.
What sets this link apart:
- Cold-forged pin collars integrated into the outer plate for chain-matched strength
- Chromium carbide layered pins for extended wear life under racing loads
- Slimmed outer plate reduces rotating mass versus older-style 520 links
- Gold finish for a direct match to the Pro Series Forged 520 Racing Chain
- Sized for full-size off-road and MX drivetrains running a 520 pitch chain
This is a master link only, meant for building or repairing a Pro Series Forged 520 chain rather than a mixed-brand chain, since the plate geometry is specific to the ProTaper design. Racers who run this chain on a full season should carry a spare link in the pit box; a bent or cracked plate at the worst possible lap is one problem this part solves in minutes. Genuine ProTaper construction, backed by the manufacturer warranty, from a shop that has raced these parts since 2005.
