Specs At A Glance

Good To Know

Q: How often should a standard chain be lubricated? A: A non-sealed chain should be cleaned and lubricated more frequently than a sealed one, especially after wet or dusty rides. Regular care keeps the rollers moving freely and delays wear.

Q: Should I check chain tension after installation? A: Yes, correct slack should be set according to your model's specification and rechecked after the first ride. A new chain settles slightly and may need adjustment.

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