Izumi Chain Half Link Adapter
The Half Link Adapter allows you to add or subtract half of one link (1/2 inch) to optimize the chain tension. It is useful when the dropout of the frames are short and also for users who would like to have their rear wheel as close to the seat tube as possible.
- Compatibility: Izumi Toughness Chain, HKK Vertex Chain, D.I.D. Racing Pro NJS Chain
