Specs At A Glance

Good To Know

Q: What advantage does an O-ring chain offer over a standard chain? A: O-ring chains seal lubricant inside the rollers and keep dirt out, which typically means less frequent lubrication and longer chain life. That makes them a good match for dirt and trail use.

Q: Will this chain work with my existing sprockets? A: Yes, as long as the sprockets are in good condition and sized for 428 pitch. Worn sprockets can shorten the life of a new chain, so inspect them before installation.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
