Iris Chain Half Link 520 - Gold
Chain Half Link - When your don't know if you got too much , or too little!
Iris RXL 520 Gold Chain Half Links.
Only the actual half link sold, this does not come with a connecting link / master link.
Halflinks and Masterlinks are Chain manufacturer specific.
Common Trials chains from Regina and Iris may both be "520" chains, but they have different pin diameters. They are still a 520 chain, and will fit all 520 sprockets front and rear, but
even though it is a 520 chain, different manufacturers have slightly different pin diameters.
The IRIS 520 links have a pin diameter of 5.15mm
This often causes problems when trying to use one brand link, with another brand chain, so please check the dimensions of your chain pins to make sure this IRIS half link will work with a non-IRIS chain.
